I had mirena. I really liked it and am planning on getting that again after #2 is here. Some people have trouble getting pregnant after it from things I havd read but it only took us a month.
After I had my son 5yrs ago I used a non hormonal IUD & plan to use it again after I have this baby. I loved it I had it put in & didn't even feel it or know it was there. The best part I didn't have my period after 3 months & that means no more cramps, which before I had a lot of. You can have it placed 6
weeks after you have baby. Good luck with whatever you decide.
I'm planning o get the hormone free IUD. The pill messed me all up & it took 5 years to conceive once I went off it. We want to try for a baby brother or sister in about 2 years, so I don't want anything with hormones.
