Deprovera

Am 30 years old I started taking Depro November 2003 I did not do any research about Depro, the knowledge I had obtained was from my GP, which was a bit one-sided, now am currently having side effects - headaches, breast-tenderness, awful cramps, heavy and frequent periods, dizzyness, shortness of breath. My next dosage is due at the end of April, I WILL NOT BE TAKING IT ANYMORE. I want to have children later in life, I really hope that taking this drug has not interfered with my chances.
