hi there Im 19 years old and am having some things happen to my body im not sure how to take. my periods are never regular at all. But for the past straight month i have had pink disscarge, then brown and a little blood here and there. my period was due on the 4th of this month in stead i had brown disscharge, then this week i started to see some spotting of blood when i go to the bath room or in my panties. also i have been extreamly tired and moody i seem to cry at anything, which is not me at all, im always feeling down! i have had some bad head akes too and cramps in my back and stomic. my boyfriend and bestfriend tell me they see a belly bump but i keep telling my self this is just some weight gain, belly chub. also im very un cofridable when i try to sleep at night i cant seem to lay like i used to. do you think this is a pregnancy or just an infection or something of that sort???
