Worried that I may be unable to conceive?

Ive been there, and done that. I was actually put on birth control at the age of 14, just to try and help control the cramping during my period. I would also miss school during my first 2 days of my period. Turned out that I do have endometreosis. As the years went by, my periods were still awful. I also now have cysts pretty bad, and they are also painful. I am on my third pregnancy though, and have had no problems getting pregnant. Actually my periods got better after my first child. I agree with the person above, you need a gyno, not a family doctor. They will check you and see what is going on. I wish you the best of luck!
