My periods are always on time. It is a 24 days cycle. My last period was from 21st to 25th January. My husband and I had sex on days between 25th to 28th January. I took an i pill on 29th January. My next period was due on 13th February. I have been having light bleeding since 8th February. It is still going on. The color is brownish. Could I be
pregnant ?
