“I started to bleed on day 12 of using the progesterone and on day one without progesterone and I already feel an improvement, most notably in terms of mood. I’m still very tired. It’s as though the commencement of bleeding flipped a switch in my brain and I feel much calmer and more like myself. This is exactly how it played out when I was a younger menstruating woman. As soon as I would bleed, the darkness would lift.”
Yes this is exactly how I felt as a menstruating woman. We now know there are several aspects to this – there is the progesterone withdrawal – which can sometimes lead to pms type symptoms, irritability, headache etc that many women got while fertile, and experience when coming off the progesterone phase of the HRT. Then there is the effect of oestrogen. During our natural menstrual cycle oestrogen levels fall just after ovulation, and then rise again falling to a low level for the last few days before the period (coinciding also with progesterone withdrawal). After the bleed starts oestrogen rises rapidly again over the next couple of weeks – but of course with HRT it stays constant.
I used to feel exactly as you did when menstruating – tense and horrible, irritable etc during those last few days and almost a day after the bleed started I could feel all of that melting away – just like the flipping of a switch – I could almost feel the sensation of the oestrogen rising - surging through my blood stream, even though I might have period pain and a bleed, and my mood became light and buoyant again.
Since being post-menopausal it isn’t quite like that because oestrogen does not rise - but I do feel the head fog clearing once the progesterone has gone (which takes a few days) and I feel bright and normal again.
“My question is that my body seems to want to bleed by itself on day 12 of the 200 mg of progesterone. Based on your comment, does that mean that I should not do too long of a cycle? I would like to extend the 16 days to, perhaps 21 days on oestrogen only.”
I can’t remember all the details of your story but if you have been checked out then presumably fibroids, polyps or other abnormalities have been ruled out.
Since the bleed is cyclical then it is likely to do with the hormone regime. You said you used to bleed too much on lower doses of Utrogestan. I presume you had a scan and the thickness was measured? If the endometrium is at all thickened or thicker than it should ideally be, then it still has to shed so sometimes this can be an explanation for an early bleed. In any case even the guidelines if I recall correctly, state that the withdrawal bleed occurs towards the end of the progesterone phase or just after – so you’re within the bounds of normality.
As to the question of lengthening the cycle – well that does depend what thickness your womb lining is, so if it is thickened – it could take several months longer to thin down so in the meantime extending the cycle probably wouldn’t be advisable, if you want to avoid bleeding problems or more thickening maybe.
Another factor to think about is how long and heavy the bleed is – if long and heavy – then there is clearly more lining to shed, but if it is short and light despite starting at the end of the progesterone phase – then that might just be how your body works and extending the cycle may mean the bleeds still start early. Ideally it would be good to have a scan just as the bleed is finishing when the lining is at its thinnest but if not, see what happens over the next couple of months – depending on the bleed.
In short – if the bleed is long and heavy then probably not a good idea to extend the cycle yet. If short and light then why not give it a go and try 21 days of oestrogen followed by 12 days of Utrogestan giving you just under a 5 week cycle?
Any concerns about anything including your bleeds, of course consult your doctor and ideally discuss with or at least inform your GP or specialist about what you’re doing.
Hope this helps and all the best
