My last menstruation was on October 14, 2011 since then I haven't had my period. I took 3 PT's and all were negative 3 different PT's and 3 different times. I notice today I had a pus like discharge (yellowish mucus like from cough) but I have no urination problem and my lower abdomen hurts from time to time but not really that painful. I am a single mom. Before I got pregnant my cycle was irregular but after I gave birth it turned normal. My child is 3 yrs old now and I'm 20 1/2 now. I have a boyfriend and the last intercourse we had was on October 27, 2011. I am really worried as to what this could be. I also can't go to the doctor since I know my mom would freak out if she knew (whole family thing). So yeah. I badly need advice. :(
