Hi, I am 28 years old and in relatively good health. I'm not overweight. I have a fairly healthy lifestyle. don't drink or smoke. I just started taking birth control . I'm on my 3rd active week and I'm having pain in my upper abdomen. Is this related to the birth control? I took birth control , a different brand, a few years ago and had similar pain and thought it was an ulcer but now I'm wondering if its something differernt.
