Hi
This happened to me.
4 months into starting patches, the bleeding began. Every 2/3 weeks, just like a period.
I had several scan and 2 hysteroscopies. All normal. No polyps, cysts, fibroids etc.
It was suggested I have a coil fitted, to allow me to continue to use Oestrogen. Reluctantly I agreed. 5 weeks on, I’m spotting rather than bleeding.
They might suggest you change your progesterone or double up on the utrogestan.
Fingers crossed it settles down for you.
