Hi, since I started Yasmin in March I have been getting stomach aches and recently they have become more frequent. They usually start when I am eating or drinking alcohol, after a few bits I begin feeling nauseous and my stomach hurts. Sometimes it gets to the point where it just knocks me out, I don't move because I might throw up and my stomache won't let me...it's not fun. So I was just wondering if this could be from yasmin? I am especially concerned because my 21st birthday is coming up and I would like to enjoy it. I would love some feedback! Thank you!
