My last period was on October 27 - November 2. My period usually last 7 days. and im on a 28 cycle. How ever i calcualated and i should have gotten my period for the month of November on the 24 but i still have not gotten my period. Me and my fiance have been having un-protected sex as soon as i got off my period. we always have unprotected sex. How ever i've been spotting for the past two days and it only happens when i push to pee. its a light pink color but it doesnt stain my panties or anything like that. its not a lot. I've always gotten cramps a week or a couple days before my period and so far i don't have any cramps or pains. My breast are swollen and i have blue veins visible on my breast. my nipples get hard by them self for no apparent reason. my breast look a little swollen. before i used to get my period my breast would just feel tender but the way they are now is something ive never experience before. The month of November is almost gone and i still have not gotten my period. I just feel tired all the time lately . i don't know if its the harmones or something else. what could this be ? and when do you think i should take a pregnancy test so that i can get better results.
