Hey I'm Payton && I'm 16.. I got on the shot about two months ago.. But I don't know if I was pregnant before.. I did a test before I got on && it said negative, but if I am or was pregnant id be about 3-4 months... I didn't drink  because I thought I was but Saturday night I had a mixed drink && bled a little.. But I have not had my period since I have been on the shot or a month before getting on either.. Any help?
