Hi there
I am just posting this in case anyone's interested in my experience.
Some of you know that I am post-menopausal and take bio-identical HRT in the form of Estradot 50 mcg patches and Utrogestan 200 mg capsules vaginally 12 days per 6-8 week cycle – ie I still have a bleed. This is with the blessing of the lovely part-time GP at the local practice who specialises in all women's gynae issues and has done for over 30 years.
After some minor bleeding and other minor problems last year which needed investigations (nothing wrong) she was happy for me to continue with my HRT, but because of the thickened lining and a small fibroid, suggested that to be on the safe side I should take a course of norethisterone once a year to “strip the lining†of the womb, as she put it, in case there was any thickening on the longer cycle. Knowing how it gave me migraines when I used Evorel sequi patches when I first started HRT, I put it away in the drawer trying to think of a time when I wouldn't mind feeling rough for a while.
Mid August I decided to take the plunge – most of my work is within term-times, and my holidays had finished, so I cast aside my “nil-by-mouth†HRT regime for the first time, and popped norethisterone pills (5mg) for 12 days for this cycle. I felt a bit weird, wired, dizzy and spaced out the first day after taking them but surprisingly did not get a headache or a migraine despite the high dose compared to patches/combi HRT pills! However I got very tired especially in the mornings (more than usual) and was very ratty with my husband (more than usual

).
Then I was worried about what the withdrawal might feel like, and the bleed. Because norethisterone is more stable than progesterone I didn't feel the effects of the withdrawal for a couple of days and thought I'd got away with it, but last Sunday I felt as though my head would explode – massive tension and headache for about a day and a half – but no migraine – so just like normal pmt. Then I started the bleed and the tension melted away as the effects of the progestogen wore off and I started to feel myself again.
The bleed is definitely heavier than usual/last time – so I am wondering if either my lining has got gradually thicker (due to the longer cycle), or possibly that my small fibroid (identified last year) has grown in the presence of oestrogen. I shan't know until next cycle.
All in all it wasn't as bad as I had anticipated although I felt quite low on the norethisterone and when I had the bad head, I just thought of the difficult choices we have to make when post-menopausal and want to continue with HRT, and still have a womb, as most of us do.
Either you throw in the towel (sanitary?

) and give it all up and suffer the consequences, or you go for continuous combined HRT and suffer the low grade side effects of progesterone without the wonderful moments on oestrogen alone, or you continue with a cycle – and suffer continued pmt both from the progesterone and withdrawal from it, and the cursed bleed – which wears a bit thin once you're in your 60's!!!
However all in all I am not complaining – just reflecting – as most of the time I feel generally well on HRT! Also noting that your body doesn't stay the same – I had no idea that I could take norethisterone and especially at a high dose orally, and not get a migraine! I'm not a convert though – it's still synthetic but maybe will take it once a year if it enables me to stay on HRT long term.
