im curious as to whether or not i'm pregnant. i've been killing myself to get legitimate answers but i'm having a tough time. for the past 3 weeks my breasts have been extremely tender. i took 4 tests too, i took one 3,2,and 1 day before my period. they all came up negative. yesterday should have been the day i started. i'm spotting but it's not a full-on monthly yet. i don't have any other real siginificant signs other than my boobs hurtin. i have a light bleeding but i'm wondering if for some reason it's implantation bleeding. do you usually cramp with implantation??
