We were planning for IUI, my doctor prescribed me meprate 10 mg for 5 days starting 21st day of my cycle. Not sure why, she gave me meprate? she said, it will help maintaining my hormonal levels balanced. I always has regular periods in 26 days. Now I completed meprate dose 4 days back, today is 32nd day and I still don't have my periods. We also had sex, am I be pregnant? I did one test and it came out negative.
