I didn’t have any side effects at all coming on or off, but I never had any side effects going on the pill to begin with. The pill I take is Yaz (Eloine in the UK) and have been for years. I never had any issues with it, and stopped it 6 weeks pre op and didn’t experience anything at all.
I think it depends on what pill you take and your own bodies sensitivity to hormone changes and side effects, as from watching YouTube videos and reading magazine articles on Contraception many do get side effects coming off the pill.
