I got Mirena put in May 16th. I had it put in while I was on my period, the insertion wasn't bad at all. Felt like a period cramp. It was over in a few minutes. I felt fine. Went home and did some laundry. I bled for another week after getting it in. Then the next week I spotted. Two weeks after that I was fine. Then my period came back June 16th. I had it again for 2 weeks. Which brings me to today pretty much. The last two days I didn't bleed, and today I started bleeding again. I know the doctor said that the first 3-6 months there will be bleeding off and on. Everything is going to be out of whack until my body gets used to the foreign object inside of me.
That is really the only issue I am having. I'll have maybe one sensation of cramping and then nothing for the rest of the day. I've lost about 7 lbs since I got it in. I'm going to hold out and see what happens. I hope after 6 months my periods will be regular.
