Pregnancy Info HOME

I stopped taking birth control pills back in November because my body wasn't responding well to them. I had a regular period in December around the 18th. Then I had unprotected sex twice last week and again yesterday. My bf ejaculated inside of me. Now today I have a brown discharge. I am not suppose to get my period for another week or so going off my last cycle. I've done some research online but am so confused because I get different results. I am unsure if my period is a week early or if its just discharge. I guess I should probably wait until its gone to take a pregnancy test. Is pregnancy a possibility? Help!!
