Hi.Just 2 days ago I had sex and yesterday I had white discharge coming out of my vagina.Also,today when I went to the bathroom yellowish/white discharge came out as I wiped myself.I haven't had my period yet I usually start around the first of the month.Today is 4-30-07.I was wondering am I having discharge because my menstrual cycle is about to start or because im pregnant?Also i'm 17 yrs.old.Thank You :-)
