I’m 28, just had my first daughter and before her I had the Mirina coil. Had no problem conceiving but it did make my period pains worse when I had it in (no bleeding just excruciating pain) so I had it out early. I’ve known others who it’s solved everything for them. I think it depends on the person but never heard of it effecting fertility.
I had a copper coil, only had it removed to have a baby (conceived within 3 months). I think they're great and currently waiting to have another one put in! Wouldn't have any other form of contraception now!
I had the coil and fell pregnant the month after I had it removed. Never heard of anyone ever claim it caused infertility x
I was told I was infertile and had previous IVF failure. I then had the Kyleena (smaller version of Mirena) coil fitted due to horrendous endometriosis symptoms. I had the coil removed in January this year to get ready for a laparoscopy and then another round of IVF but fell pregnant naturally in April. I wouldn’t take your MILs experience as gospel. I absolutely loved my coil, it’s been be only form of contraception that hasn’t made me gain weight or want to kill myself. It was a godsend for my pain, excessive bleeding and every other Endo symptom I had.
It’s very sad that your MIL had a negative experience, but it doesn’t stand for all women. I know women who have been on the coil for a number of years and still had kids after, and had great experiences with the coil. I personally didn’t have a great experience - I had to have mine removed as it became dislodged and I only found out because I was having a scan to check my ovaries, etc. I told the lady scanning me that I was on the coil and she was like nope you aren’t 🤣 turns out it was just floating around in there. But since its removal, I have managed to get pregnant (baby on the way). The best contraception that I’ve used that didn’t play with my hormones is the patch - not sure if you’ve looked into that, but I loved it and will be going back on it after I give birth! xx
