If you peri and still having periods, you need a sequi regime. Two weeks Oestrogen and two weeks Oestrogen and progesterone ( I think) to give you a predictable bleed each month.
If you are post, literally all that means is, at least 12 months no period, then you can opt for a Conti regime. Some don’t tolerate progesterone daily, so still opt for the sequi and have a bleed.
Then, there are women like me, who bleed on HRT whatever. I bleed on patches and am going to trial a Mirena. No clue how it will go, but anything is worth a shot! Apparently it isn’t a period, but the hormones influencing the womb lining. I struggle with this idea, as it looks like a period to me and sure as hell feels like one!
Anyway, good luck. I hope the bleeding stops for you.
I am also going on a beach holiday in the summer and dreading any kind of bleeding getting in the way!
