My wife is 5 weeks pregnant. she started paining in lower abdomin. We consulted gynae who suggested Beta HCG, Progesterone test & TVR for early pregancy studies. Beta HCG level was 13360 mlu/ml corresponding to 5-6 weeks of pregnancy. The serum progesterone level was 8.7 ng/ml which doctor said is very low. So She prescribed susten Inj. every 4 days. Duphaston & Foledge tablets are also given. TVR report said Cardiac activity not found but single irregular intrauterine gestational sac is seen. yolk sac is seen. please give your opinion for pregnancy to continue.
