question: Hello doctor, I had my last periods two months back. Last month, I and my fiance got intimate, though we did not have intercourse, he fingered me after touching himself, so to be safe I took I-pill next day. A week later, I had bleeding for three days. Since then I did not have my periods till date. I have taken six home pregnancy tests which were all negative. What can be the cause of delayed periods, can I still be pregnant? If not can I take Meprate tablets to start my periods?
