So i had my period on february 17-23 2010, and then on the 24th me n my bf had sex unprotected. Then March 14 I started feelin a lil pain on the left side of my vagina like i do sometimes when im going to have my period. That night I wipped n there was brown blood. This was only 17 days after my last period which is early! It lasted from the 14 to the 19 but it was super light pink n the last day it really wasnt there on the 19th it was crazy short and my periods always 7 days and on time and on the 19th there was pretty much nothing. But ive had headaches, backaches, nausea, fatigue, seeing veings in my hands n boobs, smell even better, feeling hot, lost weight, bloated, sore ribs and other crap no puking or sore boobs. Also my lips are purplish blue (Vagina). Just tonight ive felt a sharp shooting pain in my right boob. Ive been doing some searching on like baby center and other sites they said id be 7 weeks pregnant if i am. AM I PREGNANT??? like why would i have a period 17 days after my last it be so short n semi heavy for like 2 of the days.
