I'm on the pill of estrogen, spiro as my blocker, and bio-progesterone. I have a period each month. My boobs tend to get a bit more tender, bloating, mood swings, cravings, and cramping. For me IT usually goes around 5 - 7 days, but how severe some of the symptoms are varies from month to month. I also don't cycle my hormones either and my hormone levels are all fine. Even when you have a steady dose of hormones, your body is going to regulate it one way or another, which is why transwomen can experience periods. It may be more pronounced if you're on a patch or injection, but it's still likely on the pill. For me sometimes my period cramps aren't super bad, other times they suck and are the worst pain ever. But yes it's a thing, so love it or hate it, (I do both XD) you get the full woman experience.
