Mirena

Hey ladies had my mirena In today it didn't hurt one bit to put it in. I didn't get numbed at all. I have some cramping down my leg feels like a growing pain. Any ways I forgot to ask    When I can start working out again ? I need to get in shape for my friends wedding and I'm over weight due to having my baby three months ago. Please comment if you had an iud and how it went for u
