K.,
I take the Yasmine birth control pill. It is known NOT to make you gain weight. Maybe you can switch to Yasmine?
You also need to eat right and exercise on a regular basis, which means oatmeal (with no sugar - but Splenda or Stevia is okay - Stevia even better, but Splenda will be fine too, and it is sweeter) with blueberries and a glass of skim milk. Or a high-fiber cereal and fruit. You know, healthy foods like that. Follow that healthy eating pattern all day long (apple and peanut butter for a snack, turkey sandwich on whole wheat with NO mayo for lunch, and a lean meat with veggies and brown rice or whole wheat pasta for dinner. Unsweetened applesauce with cinnamon on it is a good dessert after dinner. If I am hungry a couple hours after dinner, I snack on dry Cheerios. Sometimes I put it in a bowl with skim milk. Or, unsalted, unbuttered popcorn is also a good snack. Make good food choices, exercise, and if your medical situation of menstrual migtaine (not sure what that is) allows it, then switch to Yasmine pills. Your age has nothing to do with this, in my opinion. There are plenty of skinny women in their 60's and 70's!! Good luck!
