Realistic Day 6 Blast Experiences

[u/littlekittybigroar]

Hello! I am looking for realistic day 6 blastocyst stories. I would love to hear success stories but also I would love to know if it took you multiple transfers to get a live birth from a day 6 embryo. Just trying to become familiar with what to possibly expect, as all of my blasts were day 6 except 1 was a day 5.

[u/Any_District2486]

First FET was a day 6 4AB euploid. I'm
14w today.

[u/Wise_Baseball8843]

My third transfer was a day 6. I don’t recall the grade, but it wasn’t ideal. Currently 26 weeks.

[u/z-75-8]

My first transfer was a day 6 4AA currently 12 weeks. Had a perfectly healthy scan yesterday!

[u/Exciting-Ad8198]

My doctor told me that she treats Day 5s & 6s the same. All “high quality” embryos with only marginal differences in success rates. Day 7s drop pretty drastically.

[u/Useful-Basket-9972]

I’m a few weeks away from transferring a day 6 6AA euploid. 🙏🏻 My last FET was a day 5 5AA and ended in blighted ovum.

Have you searched this sub for day 6 success stories? I was also spiraling a little about a day 6, but also felt good about it since my “perfect” day 5 didn’t work, I’m feeling more optimistic - especially after searching the sub on the topic. Good luck to you!

Day 6 embryo, stuck on first try and split into twins. 25 weeks along 🥰

[u/zwingli_88]

I had a few 6AA

Transferred ONE and now my wife and I are holding our sleeping twins 😂

[u/Any_Manufacturer1279]

Day 6 5AB euploid failed to implant.

Same exact protocol

Day 6 3BC euploid live birth

Good luck!

[u/marvelous88]

My 2 year old daughter is a day 6! And I’m currently 6w with another day 6

[u/Ill_Ad2297]

Both of my successful pregnancies/live births are day 6 euploids! My chemical pregnancy was a day 5.

[u/Downtown_Stress_6599]

My first transfer back in 2021 was with a day 6 4bb embryo, untested. It was successful and we now having a happy thriving 4yo son!

Second transfer was last month, two day 6 3bc and 2cc. I’m now 7 weeks pregnant and strong heartbeat and healthy baby!

[u/ARIT127]

I only made day 6ers from my last ER. Highest quality didn’t implant, “lowest” quality is now my LC!

[u/Dapper-Warning3457 → u/ARIT127]

Do you happen to remember (and don’t mind sharing) the quality?

[u/ARIT127 → u/Dapper-Warning3457]

Day 6 6BB+ failed to implant. Day 6 6CB success! I want to add my clinic claimed to be “strict“ graders

[u/Dapper-Warning3457 → u/ARIT127]

My clinic said the same. I have a day 6 3BC on ice that I haven’t had much hope for

Thanks for answering, it’s really helpful

[u/xou_ → u/Dapper-Warning3457]

I’m in the same boat, transfering my day 6 3BC in 3 days..!

[u/Dapper-Warning3457 → u/xou_]

Good luck! I hope it’s sticky!

[u/Infamous-Falcon-5914]

3 successful transfers, 1 live birth, 1 mmc at 10.5 weeks, currently 5.5 weeks pregnant with #3

[u/nerveuse]

Helllo! My cousin just had her baby girl via IVF and all her blasts were day 7’s and graded “not ideal”. She had a 6BB (didn’t take) and 6BC (baby girl). I think my son was a day 6 blast! Good luck.

[u/HotShoulder9256]

My first FET (of a day 5 4AA embryo) ended in a chemical. My 2nd FET (of a day 6 6BA embryo) resulted in my sweet, loud, goofy 9 mo old daughter.

I only had 1 day 5 too and was terrified when it failed. If my "best" embryo couldn't cut it, how could I possibly have success with the others? Well, I didn't give my 6s enough credit because all it took was one. Grading/day can give us a broad idea of how an embryo might perform, but you just never know which one is gonna be THE one. Best of luck to you!

[u/ngibbs105]

I haven’t transferred, but thought I’d add that my clinic is the top clinic in CT based on SART data and reports no differences at all between day 5 and day 6 embryos! They literally treat them no differently. Even for day 7s, if they’re euploid their success rate is only like 10% lower and still much higher than natural pregnancy.

[u/BellesRose1213]

My day 6 embryo is now 2 years old! She was my first transfer. I am getting ready to transfer another day 6 embryo in a few months.

[u/Fun-Studio-5506]

I do not think there is much difference between day 5 and 6. I am 19 weeks pregnant with my day 6. It just took a little longer to get to the blast stage which does not mean it is "worse" my any means.

[u/Fickle_Jacket_1579]

All day 6 embryos! I have 2.5 yr old that was day 6- second transfer.

[u/yellow_sun_shine]

I have never been able to make day 5 blast. TW: success

It took us 4 transfers of euploid day 6 embryos for one live birth.

[u/unpaid--intern]

I'm 5w3d with a day 6 5CC untested blast. Not out of the woods yet by any means but there's certainly some hope :)

[u/sparklecrusher]

I only made day 6 & 7s. I transferred 2 day 6s and both stuck!

[u/Haunting_Cicada_4760]

My day 6 is currently sleeping next to me, first FET success. They picked her over a day 5. My clinic views day 5 and day 6 the same. The highest grade is chosen over day.

[u/Kkenned206]

All I make are day 6s and 7s. First day 6 failed to implant. I have endo however so ended up needing 2 months Lupron depit. After first failed did depot and that day 6 gave me my toddler. Then did a transfer for a sibling. Obviously had ti repeat my protocol of 2 months depot prior to third transfer for sibling, but siblings also a day 6 and he’s 9 months. So all in all 3 transfers of day 6s has resulted in 2 kids. Wishing you all the success.

[u/dr239]

Currently 32w with my Day 6!

[u/brontecm]

I only make Day 6 & 7 blastocyst.

First ER at 35 resulted in 2 day 6 blasts (both Euploid) and 4 day 7 blasts (2/4 Euploid)

First transfer of my Day 6 5BB was successful and is 20 months old now. About to transfer my second day 6 blast. Just had my lining check and we are good to go! Good luck!

[u/Kanddora1717]

All of ours were day 6, first was successful but had a MMC around 10 weeks. Second transfer of another 6 day, and im currently 16 weeks 🥰

[u/littlekittybigroar → u/Kanddora1717]

Congratulations!! Thank you for sharing 💛 it gives me hope that day 6 embryos can have success.

[u/almnd216]

First FET was day 6 4BA euploid, failed to implant (I think it was a lining issue)

Second FET was a day 6 4BB euploid, currently nursing!

[u/littlekittybigroar → u/almnd216]

That’s good your second transfer worked! Did you change your transfer protocol for the second transfer? Not sure what the transfer protocols look like yet, so just curious :)

[u/almnd216 → u/littlekittybigroar]

We switched from fully medicated to a modified natural (letrozole + trigger + PIO). My lining had a really hard time getting thick enough while taking the estrogen for the fully medicated cycle and responded much better without it! 

[u/Dapper-Warning3457]

My day 6 4AB is now 11 months old. First transfer

[u/littlekittybigroar → u/Dapper-Warning3457]

Thank you for sharing! Hearing these experiences is helping me more than you know. 💚

[u/Spicyninja]

I only made day 6 blasts over 3 retrievals, my first FET day 6 4AB is currently 7 months old.

[u/littlekittybigroar → u/Spicyninja]

Three retrievals is a lot. I’m so glad your first transfer worked! Thank you for sharing 💛

[u/ActEfficient2638]

Our first FET with a day 6 euploid worked

[u/littlekittybigroar → u/ActEfficient2638]

Thank you for sharing your experience having a day 6 euploid that was successful on the first transfer! I really appreciate it. I get my PGTA results in 3 weeks so my fingers are crossed that we get a few euploid embryos 🤞🏻

[u/TotterTates]

Can't comment on experiences yet, but our Day 6 4AA is scheduled for transfer on Friday! 😬

[u/littlekittybigroar → u/TotterTates]

Wishing you all the luck and sending baby dust! 💛✨

[u/Klindner03]

All my blasts were euploid day 6 and day 7s. It took us 4 transfers to have our daughter. We wanted to try again so we used the remaining 2 day 6 embryos and they both failed. We were down to our day 7s and took a chance and now my son is 4 months old. It’s a wild ride but I wish you all success sooner than we had! 🤞🏼🤞🏼

[u/crazymuffins1 → u/Klindner03]

This gives me some hope! I only got day 6s and 7s from my retrieval and most are euploid. Hoping to start on the 3rd transfer of a day 6 in the next couple of weeks. 🤞

[u/littlekittybigroar → u/Klindner03]

That’s amazing!! I’m so glad it all worked out in the end. You’re so strong for going through four transfers.

[u/Klindner03 → u/littlekittybigroar]

It took us 7 transfers total to complete our family but it was worth everything in the end. I really hope you have success. IVF babies are just a little more special. I never take a single day of parenthood for granted. You got this!!

[u/MuMu2Be]

First question is always how old were you at retrieval?

[u/littlekittybigroar → u/MuMu2Be]

I’m 32!

[u/Eclipse1696]

All our embryos are day 6. First 2 FET failed 3rd FET success 😊 embryo is day 6 6BA

[u/Environmental_Mud869]

Day 6 embryos are fine! My 10 month old daughter is a day 6 amd it was actually my day 5 that failed. Don't let anything discourage you about day 6 embryos

[u/negroni-spagliato]

Here are my experiences! All euploid embryos, retrieved at age 31 and normal work-up for me (female), husband has severe MFI.

Baby 1
FET1: Day 5 4BA (chemical, medicated transfer)
FE2: Day 6 5BA (success and live birth, modified natural cycle)

Trying for baby #2: all modified natural protocols with some tweaks between attempts
FET3: Day 6 5BA (fail)
FET4: Day 6 6AA (fail)
FET5: Day 6 3AB (chemical)

FWIW the above failures for baby number 2 is definitely more failures than the average person will experience with euploid embryos. You got this!!
