I was on deviry 10 mg for 15 days from 11 feb to 23 feb and I had unprotected sex on 20 feb. My periods came on 24 feb which lasted for full 7 days and then my bleeding started on 13th march and it also lasted for 6 days and it was quite like a normal menses .I have a doubt whether I am pregnant or not. P.s. I had no sex after 20th feb. Pls advice me about pregnancy and do I need to take pregnancy test?
