I'm a 24 years old, Ive been on several different birth control pills since I was about 14 to help with extremely heavy bleeding and debilitating cramps. Ive had issues with cysts, had surgery for it, and been dealing with abnormal cell results for a couple years. Recently right around ovulation I experienced sore nipples, not breast tenderness, just the nipples, this has gone on for a week but has decreased, I experienced some unexplainable irritability for a couple days right around then too. Now I have very mild cramping a week before my period is due. I recognize that pregnancy is a possibility, it's too early for a test, but I have also recently undergone a very drastic diet change, and experienced some very quick weight loss, could this be part of it? Could it be something else? I have no other symptoms and I do feel like stress could possibly be a factor....any thoughts?
