I recently had surgery to remove stage 4 endometriosis. The surgeon said I have retrograde bleeding which cause the endo to come back sooner. To avoid this, I’m considering using the mirena coil to prevent period bleeds. However, my pms is very bad, I get very down, tired and seriously stroppy before my period. I’m worried that the mirena will make my moods worse as I seem to be sensitive to hormones especially progesterone. Can anyone tell me if the mirena coil has made pms mood swings better or worse for them? x
