As period delayed 2 days, I did pregnancy test and found positive. Hence from next day I took medicine to avoid pregnancy (Mefigest & Mesoprost). After three days bleeding started and lasted for ten days( Tranostat Mf was taken on 10th day to stop bleeding). Now again period is due but no sign and hence pregnancy test is performed. The test sowed negative. But I am worried why period is not occurring or delaying. Please suggest whether I am still pregnant and cause of delaying means.
