birth control
"It's birth control and I feel with every birth control I have had, I have similar side effects - low sex drive, about 10 pounds weight gain that WILL NOT go away (workout 6 days a week & eat paleo).  But, it works in controlling my endometriosis pain and my periods only last about 4-5 days.  If you start spotting, stop taking the pill and have a period! That's how you get it to stop.  I have been taking this for 10 years and I take it at the same time and still have spotting, but that's just when happens when you try to tell your body to stop a natural process. If you have endometriosis, I recommend this pill OTHERWISE get a regular, 1 month pill which will give you less side effects while still working at a method of contraceptive."
