hey everyone...i had two period on july.. and on aug 17 i got my period again.. but i noticed that nothing was coming out... well its was light red almost pink. then i noticed that the little blood that came out, turned brown. my period normally last 3 days but this time it didnt. i only had half the second day, tissue come out. and it was about a quarter size. the first weeks after my so called period i noticed my breast had a sharp pain trhough the nipple... but it was only once. now they are really itchy, i have mood swings, i feel nausea, fatigue, irratibility, and now i got hemorrhoids. these are syptoms of a pregnant woman. but the thing is that i took a pregnancy test and it came out negative. can i still b pregnant,?
