My period.....😞??

I thought I was pregnant maybe, I had a faint line on a test, missed my period 3 days.. Yesterday I had pink blood I thought was implantation bleeding.. I've been so damn moody, like I'll cry for nothing, my back has den killing me, I'm tired all the time, my stomach hurts in the middle, I always feel like I want to throw up, etc.. But today at work I went to the bathroom and didn't even feel the blood come out but it was my period... I still feel all these damn things, but oh well... I can't get pregnant obviously 😞
