IUD , Birth Control Selection Help 😩😳

Shantoria
I need real answers that would really help 
Ok so after I had my first baby and I went for my six week check up I learned I have a retroverted uterus (meaning backwards) which makes period cramps 2x's worse, sex painful etc. & I was looking into birth control after I had my second child im still young and I would like to have more kids in the future so I don't want my tubes tied I've been on pills and depo and I don't like either one the pills I'll forget to take and the depo shot made me gain weight and also going to the doctor taking a pregnancy test every 3 months was no working for me so I looked into getting the IUD because it's long term and I was wondering if anyone who has a retroverted uterus has gotten an IUD and how was the experience 
ThanksÂ
