Hello Shreya Thanks for writing to us with your health concern. By 10 weeks of pregnancy, the normal heartbeat of the baby should be around 140 beats per minute ( bpm ). 40 bpm is definitely bradycardia. IT indicates an abnormally growing pregnancy, which is about to expire by itself. Yes, your doctor is right - this pregnancy should be terminated. So a D and C is the correct procedure. The baby should definitely be sent for genetic and chromosomal analysis. This help to form a specific diagnosis, and also, thereby avoid similar complications in the future. Most women with first trimester abortions go on to deliver normally the next time. So do not worry. Avoid a pregnancy for 6 months atleast. In this interim time period, please take daily 5 mg per day folic acid tablets. Get your blood sugars tested and your thyroid hormone levels also measured. All the best. Take care.
