Everything was fine until Sunday morning. I had some spotting. Nothing to fill a pad but enough to worry. Had an ultrasound yesterday and there was a baby with a low heart rate of 63 measuring 6w1d. I should be 6w5d. Everything else measured fine. Doc said no explanation for bleeding other than maybe because husband and I did do it on Saturday night. Still spotting As of Tuesday afternoon. But still nothing that is more than when I wipe. Second pregnancy. Go back next Tuesday for another ultrasound. Heart rate so slow, not a good sign, but still have hope as no cramping or major bleeding. Please say a prayer. I’m 35 and am running out of time.
