Two months ago I began spotting a week before my scheduled period with mild cramps. The same is happening this month. I have been sexually active for the 3 years. I began rigorious athletic activity about 3 months ago and eating a healthier diet. I am concerned.
Pills have to be matched to the person.
It sounds like you and Ortho Tri-Cyclen were a good match for several years. The pill did not change but you may have. With the diet change and increased activity you body is different from what it was. Any time there is a change in the body function that is not totally understood it is a good idea to get a medical evaluation to be sure you are not anemic, that your thyroid is OK and other minor evaluations that can usually be done with the history and a quick evaluation in the office. Early spotting suggests not enough progestin in the pill you are taking and that would make sense.
