(sorry it's long) my dad doesn't want me going on birth control because he doesn't want my getting big..?

When I went on the pill my s didn't get any bigger, but my periods got much more manageable. From the sound of it, yours are a little worse than mine were, but from the age of 10 I had super heavy, painful periods. I finally went on the pill at 20 and it was honestly one of the best choices I ever made. The difference is amazing. My periods are 4 or 5 days now, they used to be at least 10 days, and once it was 17! I hardly ever have any cramps and my emotional symptoms are way less. I was actually talking to my mom a couple weeks ago about the difference it made, and she apologized to me for not having me try them as a teen. She told me "I don't know why we put you through hell like that for so many years" and that she used to have some of the same problems if she wasn't on the pill. Tell your dad you would like to give the pill a try to see if it helps you, and if they don't work or you start having unpleasant side effects you'll go off them. Maybe have your dad talk to your doctor to get the lowdown on what's going on with you and how severe/ abnormal these symptoms really are.
