Stressing

Paige

So I'm stressing because for the first six months of this year my periods were pretty regular but this month I haven't gotten it yet! I was supposed to get it on the 8th, but nothing. Luckily I work in a lab so I was able to do the HCG blood test on myself, and it was 0. I just don't know why I haven't gotten my period yet and it's stressing me out!
