About a week ago I had what I thought was implantation bleeding. I have irregular periods so I cant say if I'm late or not I just know that I haven't had a period since June. I figured that little spot of blood when I wiped was me fixing to start my af but here it is a week later and still nothing, I do on the other hand have the very super sore nipples, very very very little cramping, bloating, and irritability out of this world. I keep thinking that when I go to the bathroom that I'd have started but so far no cigar. I just took 3 dollar general pregnancy test from the same cup of urine and all of them said negative so my question is, is it more likely that its too early to detect pregnancy or those negative test are most likely true? ?
