IUD after birth?!

Lauren • Expecting my first baby girl June 19th 💕 in love with my best friend 👪
So 2 weeks after delivery I started my birth control pills. I started gaining weight just like the last time I was on them and so my Dr recommended the IUD Myletta (I think is what it's called). I got it put in Monday and since then I've finally had bowel movements semi regularly 😭🙏🏼 anyone else?? And what is your experience with an IUD?
