I had unprotected sex (he didn't ejaculate, just pre-cum) and then approximately two weeks later started having light bleeding. It lasted about a week...I heard implantation bleeding can last that long, it just depends on the person. It was either brown or pink in color, no red...It wasn't like a normal period for me at all. It was extremely light instead of heavy and didn't come with any strong, painful cramps. It also came a week earlier than I expected my period to come...They're usually very regular and i've never had spotting occur before. I should've had my regular period start on the 28th and it didn't. Now I have sore breasts, increased vaginal discharge, bad mood swings, a little bit of nasea on and off, and slight cramping...It doesn't really hurt, but I can feel it. I tested tuesday and got a negative result. It's been over a week since my regular period should've come...Is the test right? Or is it possible that i'm pregnant? Has anyone had anything like this happen before? I'm 17, but i'm mature enough to know that if I have sex then I need to deal with the consequences and i'm ok with that...I just need to figure out what's going on so I can figure out what to do.
