I went in for an ultrasound today, based on ovulation I should be around 6w4d. They found a heartbeat, but it was only 85bpm. The ultrasound tech had a radiologist come in to look, and she told me that it was extremely worrisome to have the heart rate be that low and likely a sign of fetal distress. When I followed up with my RE afterwards, though, he seemed unconcerned about the heart rate and said it was more or less normal. In contrast, he said he was very concerned about my SCH causing a miscarriage, which the tech thought looked better (sigh).
My follow up scan is in two weeks. I know this is the sort of thing where it can go either way and there's just nothing to do but wait, but I guess I'm curious what others' experiences with this have been. Thank you!
