I found out at 8 weeks that I’m pregnant with twins, (im almost 10 weeks now) and my obgyns nurse practitioner said that the second one doesn’t look “normal” but they both have strong heartbeats. The one that is measuring perfect has a 170bpm and the one that is measuring 2 weeks behind has a 165bpm. My question is, did anyone with twins have one that was measuring so far behind and be okay? I go back the 27th but I can’t stop thinking about her saying how not normal it is. I have attached my sonograms. The two on the left are of the baby measuring normal baby A. The two on the right are of the baby measuring two weeks behind Baby B (I believe you can see part of baby A in this one as well)
