Does mirena coil cause tender breasts?

Overall helped to regulate my periods, but also had significant side effects on my food intake/weight and on my energy levels.

I’ve had the mirena coil for about 7 years now and had 2 fitted. The first one worked like a dream, hardly noticed it. Since having a new one fitted over a year ago the side effects have been increasingly annoying. Acne for about 2 weeks per month, and I was never spotty before, not even as a teenager. Also period cramps, but it has completely stopped my period. Also migraines with aura, although I did suffer from these in the past, I’m not sure if they have just gotten worse or if it is the new coil. I’m very disappointed as, like I said, the first one gave me no issues at all.

For the most part, I love the mirena and of contraceptives I have tried, it’s my favourite by far. I like that you don’t have to think about it too much aside from checking the strings. It doesn’t have an impact on my mood like others did. The only drawback is random cramping I get with it that feels quite unexplained and not tied to my cycle. It can be quite sore and after reading other women’s reviews online, it seems quite common but like a lot of contraception symptoms, unexplained.
