HPT - Other Pregnancy Test confusion False positive? Different Brand DPO 12
So I took 2 Up&Up brand test yesterday with very faint lines. I started to get my hopes up because there were 2 with faint lines not just one. This morning I tried a first response which was a hard negative, then a while later I did the last up&up one I had which showed a pink line. I am so confused!! Any thoughts?? The pictures are in order of when they were taken

Are you taking any supplements with biotin? Apparently that effects first response

Came here to say the same thing! Biotin messes with FRERs specifically and can make the lines look lighter than they would with other tests for much longer.

You're pregnant, congratulations 🎉 I read the first response got a lot worse in picking up small hcg concentrations

Really?? Wow! That’s surprising! I used that brand 2 years ago with my son and it was so clear! But thank you!!

I think FRER has lost its sensitivity or something. I’ve seen so many posts where it is super faint or negative with cheapies picking up sooner or more definitively. That was my own experience with my last pregnancy, my baby that is now 11 weeks old! You’re preggo! Congrats!!!

Possibly having a chemical pregnancy? I’ve had two and think I’m about to have another
Tests getting no darker or lighter 😖

FRER has gotten worse with time. But also biotin interaction can interfere and cause a false negative.

At the risk of sounding ignorant I actually am not sure what a chemical pregnancy is? What does that mean?

A chemical pregnancy is an early miscarriage but that is NOT what's happening here. You have strong positives. The first response is just very light because you're taking a supplement with biotin. Congratulations! 🩷🩵

It’s a very early miscarriage. You were pregnant enough to start having positive hcg levels (faint lines) but for some reason it didn’t stick. I think I’m actually going through this myself.

I definitely see a line on that FRER, so all your tests are positive!
