I Need Help ASAP

Mo

I started my period when I was 9 years old. I am now nearly 21 years old. I had my daughter 2 years ago. So my periods are quite regular now. I am on birth control. But I have a problem.

I am very nauseous, barely can eat anything, my tummy upset, i have bad bad back cramps/ pain, and I just noticed blood when I went to the bathroom. I just got off my period and I never spot or bleed when I’m off my period. Last time this happened, I was pregnant. I feel like I’m going to throw up and my back hurts so bad. Like im started my period again.

My period was September 2nd - 7th (which is normal for me) so I just got off my period.

Has anyone ever had this problem? I don’t think I’m ovulating yet, it’s barely been a week.

I’m scared I’m pregnant or something!

Does anyone knows what this means?

Thank you!
