Hi Booblet
Sorry to hear about your symptoms, but I am more concerned that you are using progesterone cream for endometrial protection which is NOT recommended by the British Menopause Society, nor is there a licensed product, though you say this is correct according to NICE?
The important thing to note is that there is no magic ratio of oestrogen to progesterone because it all depends on the type of oestrogen we are taking, and the type of progesterone - it is not a question of being able to calculate gram for gram etc, so if someone has said this is the case, then I would say you have been misled.
What is crucial is that yes, the amount of progesterone needed to protect the endometrium from overthickening due to oestrogen stimulation, is dose dependent ie more oestrogen needs more progesterone (higher dose, longer duration), but this can't be determined from the actual products - hence we have a licensing system for each progestogen or HRT product which is determined through trials.
Of course the other alternative for those with the funds is to do it yourself and ensure you have regular scans to check the womb lining so perhpas this is what you are doing?
What I'm trying to say is that unless you have ascertained yourself through scans that the cream you're using protects your endometrium long term, you can't necessarily work it out through calculating a particular amount - ESPECIALLY in the case of progesterone cream which is not recommended - because of variable and inconsistent absorption.
Irrespective of Covid, (and sorry to hear about your post-Covid symptoms), the fact that you have been bleeding indicates that the progesterone cream is indeed not protecting the womb and I would urge you to go to the doc and be referred for a scan. Please don't be frightened, but you do need to get checked out and make sure you are taking an adequate dose of progesterone, if your womb lining is shown to be thickened.
How long have you been on this regime?
