I was not on Yasmin, I was on Aviane...if ANYONE on birth control ever comes down with a case of gastritis STOP YOUR PILL immediately! It is caused by the pill, I was on Aviane for 5 years ; apparently that was too long. I now use the nuvaring which is a lower dose or hormones and I love it.
I have never been so sick in my life; I was severely nauseous every single day of my life, never knowing it was because of the birth control pill. If you ever get sick after being on a birth control pill for too long, get off of it and go to a lower dose. Believe me .. do not waste your life being sick!
