I've had an IUD (Mirena) for 3 years. Since getting it my periods have been 1 to 3 days and so light I rarely even need to wear a pad. I didn't really ever have cramps, but did have ovulation pain sometimes. I'm in the middle of my first period since surgery. I had to go and buy tampons for the first time in 3 years because my flow is so heavy. Its been 3 days and shows no sign of slowing down. I left work early yesterday thinking I'd eaten something wrong or too fast. It was actually cramps. (I feel like I'm still learning my new digestive system, I didn't think the pain was from my reproductive system!) I have had my first set of labs since surgery. Everything was fine (elevated liver enzymes, but all my vitamins levels are good). Has anyone experienced anything like this? Any ideas why? Should I follow up with my gyno? My period is so far still lighter than it was before I was on any kind of birth control.
