Hi there
I don't know the answer I'm afraid however I am aware that if you are still having your own cycle, the hrt cycle won't override it.
You can try and sync them so you only get one bleed a month, that's what I do but sometimes I'll get a bleed before I've finished the 2 weeks progesterone and this month I started bleeding before I even started progesterone. It's very annoying tbh and I'm not sure there's much to be done about it as cycles are all over the place in peri xx
