I'm 17, two weeks late for my period, but I have taken two pregnancy tests and both came back negative. My boyfriend has never finished inside me, but I know that you can get pregnant from precum, but it's rare. My last period was on Oct. 7, 2008 and before that Sept. 6, 2008. It did jump around earlier this year but it was never really this late. I don't feel pregnant. I broke out the week before I was supposed to get my period, the week after I was supposed to, and now it is clearing up a little. The only other symptom I have is sore breasts. Which is another sign I usually get before my period. Although I heard this can happen when you're pregnant. I'm not sure what's going on with my body. I was stressed the week of my period (a death in the family), and now I'm worried about getting my period. Has this ever happened to anyone else? I figure if it doesn't come next month, I'll go and see the doctor. Any advice would help though.
