@edemamequeen I can only reiterate that I was told by my expert consultant gynae (15 years ago) that you override your own periods when you use HRT.
Look at it this way...
women using patches or tablets, don't 'skip' the patch or tablets that contain a progestogen, and wait for their next period.
They carry on with the 28 tablets in the strip, or the patches in the box (where half the patches are estrogen-only and half are estrogen + progestogen.)
Just because you are using two hormones that come in 2 packages, doesn't mean that you fiddle around with the regime trying to work it around a cycle.
It should be obvious that this won't work long term. Your periods might be every 4 weeks now but soon they could be 6 weeks, 8 weeks, 12 weeks apart and longer.
And you will never know how long that gap will be, until it's happened.
You need to choose a day (go for mid cycle if your period is predictable. Say that was 14 October, then that is Day 1. Take 12 days of Utrogetan then and the next Day 1 is 14 November.
