Just got off my period and now I have it again!

(Warning; Explicit)

I'm so fucking aggravated, I JUST got off my period not even a week ago and I have the shit again. I missed 3 days of birth control is that why I got it again? Will I have this shit for a while nother 6 days? I'm freaking the fuck out like not only are my periods 6 days long but they are fucking painful as fuck even with the birth control and I get fucking emotional as fuck too like I feel like breaking shout and at the same time I wanna bawl my eyes out!!! WTF?!?
