My period would normally come in the first week, of every month . This has been constant until the first week of this month;I realize that i was late on my period. I was going under alot of stress so  I wasn't paying much attention and i thought it was stress why my period didn't come as yet .However my cycle is probably weird cause i only see my period for only three days. So after the first week ended  i thought what happen to my period, so i bought a pregnancy test which it said no then i started feeling alot of pain in my belly bottom and alot of lower back pains; my nipples were unusually pointing straight as if I was cold or in heat for sex,and my temperature was really warm. On the 12th of this month i saw blood in my under wear it came very light not like how i would normally see my period would look, but i bleed for one day and on the second and third day it was discharge but pinkish or brownish i guess...o well i went to the clinic and they said that i should buy another test so they didn't help me but i bought another one yesterday and it still says no and I'm still feeling back and tummy ache so what do you think am i pregnant.....?
