Adden, I know everyone's situation is different, but I got a tubal ligation done with DD2. I definitely know I am done.
The Dr did say though that if I wanted to have anymore kids I'd have to go through IVF 😏 Hellooo! Just did that. (reversals are expensive and not guaranteed with TL).. I wanted it for me (we have MFI) we cant get pregnant naturally anyway, so it would always have to be IVF if ever we changed our minds - so really not an issue. I just felt I would not want kids to anyone else and I'm happy with 2, with my luck we would have a miracle 3rd naturally if I wasn't 'fixed up'.
I didn't want the mirena for that very reason (hormonal headaches, bloating etc that I couldn't control) hate condoms, the pill, etc, so it was really the only logical choice for me.
Maybe you could try the copper IUD? It doesn't have the progesterone like the mirena...?
