Currently 5 weeks 5 days pregnant (baby's growth showing 6 weeks 2 days). Two days back I had brown spotting and was diagnosed with choriodesidual separation of 0.01 cc. Dr. recommended hucog 5000 iu injection twice a week for 4 weeks and emergency USG on bleeding characterized by fresh blood. Last night had bleeding and got a repeat USG in emergency that showed an increase in separation to 0.02 cc but the baby had a strong heartbeat of 122 bpm. Since the diagnosis of pregnancy I have been on progesterone 400 vaginal suppositories twice a day, folic acid, thyronorm 50 MCG and complete bed rest. I have a h/o ectopic pregnancy in 2013 and cervicitis. When I found out about my pregnancy I had just completed a course of rifagut and was still taking neksium which I immediately stopped. Is it safe to take these injections as it is classified as a class x drug by CDC as it causes birth defects? And why could the baby be self aborting? On reading online I found this usually happens if there is a chromosomal defect. Please advise, very worried.
