Well my period has been late my last period was on march the 31st. I only been with my boyfriend once on april 16 and 17. (Since he lives 6 hrs away from me we don't see each other that often)So like I know myself I am an exact person that every month I get my period and this time it's been more then a week. I have taken 4 home pregnancy test and they all say that I'm not pregnant. What do u think I should do?
