This is my second time bein on the depo shot, the first time I stopped taking it was november of 08 and got pregnant with my daughter a month later. Well this last time I missed my appointment on the fourth of this month and had unprotected sex. Is the shot still in my system and could I be pregnant? I'm not havin any symptoms just yet cause I just had sex this past week but my stomach hurts really bad like it did when I got pregnant with my first.
