I spoke to soon AF just came .

Brittany • Mother to my little man . Wife to his wonderful daddy . 19 .
So last night I thought I noticed a tinge on blood when I wiped but then i didn't think anything else of it . But then a minute ago I went to the bath room and I had blood on my panties but when I wiped it was a dark brown color . Normally my period is bright red then the day it's a rusty brown color . I am cramping though so I'm sure it's AF . But at least the anticipation isn't killing me anymore and we can start over this month I just don't know how to calculate when ovulation will be , bec my last period was January 31st. ??
