Hi,I m 29yrs old,trying to conceive. ultrasound showed normal uterus and ovaries.my follicle size increased to 2 cm on day 16.I was given Inj. Hcg ON DAY 16 and then after the follicle study showed that it had ruptured 2 days later,was started on susten 200.today is day 32,no peroids but pregnancy test was negative.is it possible that i am pregnant or are my periods delayed because of susten?
