How’s ur PMS post Mirena?

I’ve been thinking of getting mirena MAINLY bc I don’t want to deal with PMS( mood swings, SPIKING appetite, bloating)

The question is since mostly mirena is used to treat HEAVY flow, what happens if my flow was NORMAL to begin with?(it lasts 3-5 days, normally heavier on the first 2 days)

I’m 21 and NEVER been on any forms of birth control before,(never had hormonal acnes) I’ve seen many mixed reviews I do understand everyone react to it differently.

I’m afraid it will fuck up my body. Anyone here had a normal period before mirena ? Please share your experience 🫶
