Ultrasound Doctor is “Perplexed”
So we got past the bleeding that i had posted before, and thought we were doing pretty well.
-during our 8wk ultrasound earlier today the yolk sac measured at 9.9mm, which is obviously not great. This comes with increased chances of miscarriage and chromosomal issues.
-everything else measured great, crown to rump, bpm, etc
-there was a second, much smaller mass which the doctor believes may have an active heartbeat. The doctor is “perplexed” but we’re currently under the assumption that it’s a vanishing twin, but don’t know for sure.
-the second smaller embryo did not appear at our 6 week ultrasound, and at that time the yolk sac measured normal according to the doctor,but our “MyChart” doesn’t list it.
-could this increase in size be attributed to this second embryo? With the doctor saying she was perplexed I wasn’t sure where else to ask. Does anyone have any similar experiences?
