Throwing up

So a while ago I was on the pill, like around 4 months ago. The first month I went on it. I threw up on the second day. And then the second month being on it. Same thing. So after that I stopped it. Cause it was terrible. Now, just of 2 days ago. I started a new brand, the brand I’m taking is lower in estrogen. But again. Second day. I threw up (which was literally 15 minutes ago.) I’m scared I won’t be able to take birth control. Or if I have a real sensitivity to estrogen. I need help. And if anyone went through the same thing!
