Hello, I am 20 years old & have been with my boyfriend for a year. I usually get my period at the end of each month, but February's didn't come till March 3rd or 5th (which was a week late) & lasted approx. 5 days. I am still waiting for my March period which i was suppose to get this April 3rd or 5th. I have a a 28 day cycle & they are regular. Can anyone help me and give advice on what could be going on & obviously if i could be pregnant?
