I need help PLEASE

My Dr has put me on a birth control that I once was on before and it’s making me so sick to my stomach.

When I was on it the first time I got sick for 2 weeks but then it got better..

This time I’m just VERY nauseous...

The only reason I am on this is because I want to have sex with my fiancé (he will be husband) on our wedding night...

is there any other way to make this easier?!
