Period + vomiting normal????

Right ladies, so for the past 3 months on the first day I have gotten my period I've been sick 🤢. Throwing up. Vomiting. And just wanted to know is this normal? Because it's never done it before. I get 1 time is just strange/or a bug. But 2 times is just strange but 3 times to me something isn't right. So has anyone else do this? Or does anyone know why? Do I need to go to the doctors about it?

Btw I'm 18 and have had periods before. And I'm not on any birth control.

Thank you if you can help me out xx
