My last menstrual period was on 30th january. And my cycle length is 30-32 days. I had protected intercourse on the third day of my cycle (1st feb). Then again on 2nd feb. I took an ipill after each time just to be sure. (2 tablets in total. I haven?t gotten my periods yet. My due date was 1 march. So my periods are 10 days late. I took home pregnancy test twice and it came out negative both times. Why am I not getting my periods? Please help.
