My last period date was 10th February, that lasted for 5 days. have regular period cycle of 28 days. I had protective intercourse on 16th, 17th of February without any contraception failure. Took i pill on 16th only as a precaution and got bleeding on 23 February till 27 February. My new expected period date was on 24 February and i am 4 days late and yet there no sign of them. Took a
pregnancy test on 10 March (23rd day from 16th feb), on 20 and 21 March and today (27 March i.e. 39/40 days from last intercourse) all came out negative. Can you help me what is going on?
