What is wrong with me.

Pooh • In Relationship 💕. Puppy mommy🐶. Junior in college 💼. Wants kids so bad 👶🏽. Loved turtles 🐢💕😍
I have a period but a very irregular one. I'll have one for very month like for three months. Then for the next two months no period. Not pregnant or nothing! It's crazy. Then it'll repeat itself all over. I have a regular length of a period. 5 days bleeding, and normal cramping and everything. Help me please.
