Ovaries help?

I think the best way to explain what's going on is to explain what happened in February. I usually have mine towards the beginning of the month, like I was surprised by the secon of February and it hadn't started. On the 22nd, which is my birthday by the way, I was horribly shocked to start. I'd had the pain for like a week beforehand though. So questions 1: Is getting that pain early normal? So I started on the 22 and I reminded finishing on the 27th -28th. Second question: Is it normal that the pattern of when they are changes?. I had another one a few days later. Question three: is it normal they fall a week apart?. It's now March 19th, and after being in unbearable amounts of pain, I started again. Last question: Is it normal they fall within the same month?

I know things like loads of strenuous excerise and stress can cause irregular periods. I do three hours a fucking week goddammit. Okay, stress maybe. School's been fucked up and this pain is too much.

JESUS I THOUGHT OF ANOTHER QUESTIONS!!

Is it normal the pain makes me physically sick?. I'm gone with the blood and all but the pain makes me actually vomit. Anyway. Thank you of you can gives me answers :D
