Okay, I started my period today, a week earlier than I should have, and I've been having slight cramps.

I usually have severe cramps and heavy bleeding, however this is light bleeding and minimal cramping.

I had unprotected sex a week ago tomorrow.
He did not ejaculate in me, though I know it doesn't matter whether he did or not. I just am assuming it cuts my chances a small fraction.

I know in any instance of sex, protected or unprotected there is a risk of becoming pregnant. However, that's not the point, the point is I did have sex, and now I'm confused.

Can someone please help me. I've been stressing out, and I know that is supposed to cause late periods. But this period is early, going against that.

I have been on vitamin C pills, which also can jump start a period. If this is the case, would my period be light since my body isn't used to starting this early? Or should it be normal?

Can someone please give their opinions on whether or not I am pregnant.

I'm extremely worried about this.
