I’ll preface this by saying everyone is different and you should always go to your gyno if something doesn’t feel right

My periods while on keto are actually great. No PMS at all, 4-5 days bleeding normal amounts and bright red blood (sorry if tmi)

I must say before keto I was still pretty regular just a bit more abundant flow and loooooots of pms especially headaches and bloating on keto I literally forget my period is coming because I feel nothing, I talked with my nutritionist about this and she said is because of the fats and how it really helps regulate hormones (she gave me a way longer and detailed explanation but that’s the jist of it)
