Yes, in the exact same boat as you!
I went 11 months with no period before starting on the conti regime of gel and utrogestan. After 14 months I stopped as it was a faff and not working ( still no bleed)
Then, I started patches
Bang, the bleeds hit me every 2/3 weeks, with pms, pain, bloating, the lot.
I had scans and biopsies, which were clear. This went on for 13 months until I could take no more.
You have two options I think.
1. Switch to a sequential regime as you have suggested. That should give you a more predicable bleed each month.
2. Have a Mirena coil fitted
I’ve done neither and swapped to lower dose oral Hrt. I’ve already had a bleed from that ( but did add extra oestrogen via a spray so am hoping that’s the cause! If I bleed regularly on this tablet, I’ve no idea what to do as I don’t want regular periods again ( or a coil)
I feel your frustration totally.
Good luck.
