So my understanding is that the Utrogestan bleed is not a period. That HRT overrides your cycle, so your ‘normal’ periods prior to HRT aren’t really relevant.
That is right. It's a withdrawal bleed and not connected to a normal period.
I’m 49, taking 2 x 100mg pills per night, and 2 pumps of Oestrogel
In your first post you said it was 14 days.
Which is it?
It's not really an issue not to bleed although if it carried on for many months, I think my consultant would be suggesting a scan to see if the lining was thick or thin.
It's possible that the dose of gel is not enough to make the lining thick, especially when you're doing the 14 days on Utrogestan and 14 days off.
This is not actually how many specialists prescribe it. They'd suggest less.
The dose (as per the leaflet) is 12 days per cycle. 14 days is 'reserved' for women who need more to reduce bleeding.
Although the product licence is based on a 28 day cycle, most women do not (naturally) have 28 day cycles ( before menopause.) 28 days is an average but the norm can be from 24 to 35 days.
Some specialists would suggest 12 days Utrogestan per calendar month.
The 14 days on and off is really a new 'guide' for GPs/women to follow easily. It didn't used to be like that - it was 12 days.
If you want to have a bleed, I'd suggest doing 12 days and within a month (so you're going 2 to 3 days longer than 28) starting on the same date each month.
