birth control
"I am over weight and I have Poly Cystic Ovarian Syndrome. So this could be why I had such a bad experience. 
The first two months were great, I had no side effects and my period even stopped. (I had my implantation while on my menstrual cycle). 

Then month three hit, and I had a normal period.

Month four started and I had a period again, however it never stopped.  After a year, and 8 months of heavy bleeding (I was using depends because I was bleeding through o.b. ultra tampons combined with an overnight pad). The doctor who implanted it just kept telling me it would stop eventually and to take ibuprofen to slow the bleeding.  It took 8 months for me to convince an on/gyn to remove it, they only did because I had become anemic."
