Coming off microgynon, help!

Hi!

I’ve been taking microgynon since October and I felt my mood get lower and lower, and stopped feeling myself. This started affecting my relationship so I’ve decided to stop taking the pill!

It’s been about 3/4 days and I’ve started my “period/withdrawal bleed” and I’m suffering from really sharp chest and stomach pains, alongside constipation and trapped gas. Usually on my period I’m the opposite!

Are stomach problems a common experience coming off of birth control or could this be something else at a suspicious time?
