I need more information than what you have provided to answer whatever particular question you have

My last period was 8-25-2009. I am now 2 days late. My menstrual starts every 28 days, like clock work. I took a test but it came back negative.

do you know when you ovulated?

i think it was between the 5th and the 10th of ug. My boyfriend and i did have sex durring that time.

My breast are not that bad anymore. I think if i were pregnant they would still be soar. I have cramps in my back now and when i wipe myself there is light pink. I think my period is about to start but i don't know. It normally just comes on and this time it seems to be taking its time.
