Hi, I mandi I have irregular period sometimes and some times it come on a stead date. However I have my period on the 22 of February 2015 and my next due date is march 22,2015 my period normally last for 7days I haven't have my period for the month of march. Its now the 4th of April and I still haven't have my period, I have backache breast beginning to get tender since 3days ago and I'm having some slight cramps like when I'm going to have my period. So I do a pregnancy test on the 3 of April and it comes out negative, could I be pregnant?
