I am 6 weeks pregnant and having pcos, the increase in HCG is 30% in 96 hours, and at 5 weeks 5 days transvaginal scan only the 6mm gestational sac visible and the yolk sac, fetal pole were not seen( also HCG doubling every 48 hours during this scan, after that I'm facing low rise in HCG level) @Dr Priyanka Patel
