Last time i had sex was 2 months ago (with condom + pull out before ejaculation). Had severe mental anxiety for weeks after and period was delayed. I got withdrawal bleeding last month for 6 days (moderate flow and there was clots on day 1) after taking hormonal tablets prescribedby doc. Did beta hcg 5 days back and it said 0.60.. do i still need to do ultrasound to rule out any pregnancy? All my upt tests and bhcg all came negative in the past 50 days.. is ultrasound necessary??? Is ectopic pregnancy still possible??
