No, you're not being thick at all! I think people get confused as some of the terms used are a bit clunky!
All HRT is 'combined' (that means using 2 hormones - estrogen and progestogen.)
(I'm saying 'progestogen' as that is what they are. Being really accurate only Utrogestan is a progesterone.)
Combined HRT - is cyclical Estrogen daily +12 days progestogen/progesterone.
Combined continuous- both hormones (combined) continuously ( daily). The no-bleed sort.
Why have you been taken off HRT? It's not necessary to stop HRT before any investigation.
If you are using sequential, your lining will be thick. It's growing each month because of the estrogen.
To get an accurate reading of the lining, it should be done as soon as the bleed is over, so that's anything from Day 5-8 of a cycle (where the bleed is Day 1.)
If it wasn't done then, the reading is meaningless because the lining can grow much thicker over the cycle. There is guidance on this which states the cut-off points depending on HRT or no HRT.
I was told (personally) that they allow up to 10mm for women on cyclical HRT before getting concerned AND a good consultant can tell a lot from a scan (thickened area, irregular surfaces, etc.)
