I had a Mirena put in after DS1 was born, removed 14 months later when started TTC DS2 and absolutley loved it.

Libido - I didn't notice any change in my libido at all. I'm not sure about CM as I was also b/f so that was affecting my CM. From memory after I stopped b/f I don't think there was any change in my CM.

Insertion - I had mine put in at my obs office on his table. I didn't have any analgesia before, during or after. I found it like having a long pap smear. It only took about 10 minutes. My ob pushed his chair back and stood up - I thought he forgot something but nope all done.

Removal - Super quick and didn't feel a thing. Once again like a pap smear. No pain before, during or after.

TTC - They wouldn't tell me when my fertility would return but I fall pg first month after having it after (My other two kids took 14 months and 9 months).

Few other things:
- If you haven't had any kids they need to insert it under a GA
- Spotting for up to 8 weeks after having it put in
- It can fall out with your menstrual cycle bleeding so you need to check it regularly
- Don't panic at the size of the box as it's huge! It has the tool to insert it as well.

I loved my Mirena and wouldn't hesitiate to get it again. Good luck with your decision.
