Period + sex = SEVERE CRAMPS

I’ve heard that having sex on your period can help with cramps, not sure where I heard this...but I’ve heard it a lot.

Anyways, couple days ago I had sex with my bf while on Aunt Flo. Not even 10 minutes later, I began feeling weak, cramps kicked in severely, and I began bleeding x10 more.

The cramps were so bad I couldn’t stand, sit, lay down, or anything. I curled up in a ball for an hour waiting for the Advil

To kick in, and even cried at one point. That’s how bad the pain was.

Is this normal?
