my boyfriend and i usually having sex every week, we've been doing this for almost 7moths with the withdrawal method, My period is irregular and now I don't know if I am pregnant , I am just wondering Why my period is not coming ,the first day of my last period was on November 3rd , and our last intercourse was December 2nd, past few weeks I become low blood and anemic due to lack of sleep because I am really stressed, Is it why am i not having my period because of stress or an i pregnant?
