I have been experiencing bleeding since Sunday afternoon, which began as spotting and has increased to fairly heavy red bleeding with cramping (much like my period, but no clots thus far). I had an ultrasound with my OB this afternoon, where they were able to see baby’s heartbeat (hard to measure, but doctor said somewhere around 100bpm), however baby is also measuring behind at 6w1d when I am roughly 7w3d based off of LMP. They were also unable to give me an answer as to where the bleeding was originating from, and did not see any sign of a subchorionic hematoma (maybe it was missed?). This was an unassisted cycle, which means I may have ovulated later than I believed I did, which would make sense. But, coupled with such heavy bleeding and pain, I am feeling very discouraged. Should I prepare for the worst?
