I am 31 and have been on birth control for 6 years, prior that I have had one child, he is six now. I also have had such a huge ovarian cyst (the size of a softball) and had to have it surgically removed. Between all that and my age, I wonder if I've passed up my chances to I crime over the past most fertile years of my life. I'm also worried that the be might cause a higher risk in birth defects.
