Liletta IUD

Mya

So I’m scheduled to get the Liletta put in at the end of this month. Pros and cons?? Has anyone had any issues having it and breastfeeding? What should I do to prepare for insertion?! I feel weird about having a string hanging so I’m on the fence if I should go through with it or not. But I have two under two and don’t want to risk getting pregnant anytime soon as my son is only 7 weeks!
