Hi MaryG
Sorry to hear about your headaches and migraines - I can sympathise as I get them too. I get the other type - the classic ones - never had aura. I just get the aversion to light and sound as one is coming on, then I get the headache and feel nauseous and an incredible feeling of exhaustion lethargy, heavy head, stiff neck etc It usually lasts for 2-3 days and wakes me at the night when the painkillers have worn off. I only started getting these during what I imagine was peri-menopause although I didn't know it at the time because my periods were still regular. They occurred pre-menstrually then - so could have been due to the progesterone withdrawal or the oestrogen dip.
However when I started on HRT, I first of all started getting them on the progesterone withdrawal phase - couldn't have been an oestrogen dip then because oestrogen is constant on most types of HRT. Then I began to get them sometimes on the progesterone phase itself - but not always! The one I've just had ( finally disappeared around lunch time today) was during the prog phase (Utrogestan). Sometimes now I even get them during the oestrogen phase too - so I really don't know why they appear and not at the same time/hormone combination each month. Alchohol can bring them on - by that I mean a very small amount eg a small glass of wine if I have it say after 9 pm - but not always. I didn't have one at all over Christmas and had lots to drink then
The levels of even natural progesterone that we have to take in order that systemic concentrations are sufficient to keep the endometrium thin means we are taking more than we would produce naturally to do the same job - which gives rise to the side effects.
I think externally given hormones can have different effects from our own endogenous hormones, so even natural progesterone (like Utrogestan) can cause a headache (like it can do to me) when one never experienced symptoms from taking it during our fertile years. This must be what is happening with you as you never had PMS problems but reacted to Utrogestan? I never suffered from progesterone intolerance - just the normal pmt that most women experience for a few days just before the period as the prog crashed (and the oestrogen dipped!).
Also apart from the first 3 months of HRT (and 12 dyas of norethisterone last summer to "strip my lining" I have never had synthetic progestogens either.
My GP told me that drop in oestrogen levels can cause headaches and equally, externally given oestrogen as with HRT can cause headaches if the level rises too quickly even though this doesn't happen in our normal cycles when fertile.
So it's no wonder we can't work it out!
Re your bleeding even without progestogens - did you have the lining measured at any point? The bleeding may have been due to oestrogen breakthrough bleeding which can occur if the lining gets too thick so not especially a good sign! I imagine as you are with a specialist your lining is being monitored? I expect you're seeing someone like Studd or Panay by the sound of things?
I agree a hysterectomy is somewhat drastic and me I just put up with the headaches - but I am on a longer cycle. I take progesterone (Utrogestan) vaginally 12 days every 5-8 weeks so this does limit the exposure and side effects. Perhaps 8 weeks would be too long for 3 measures of gel - but maybe you could manage norethisterone for say 10 days in 8 weeks or something - if the specialist agrees? I know that longer cycles are sometimes recommended by private gynaes for women such as yourself, when they can give you regular ultrasound uterus scans. I know some specialists are not that keen on longer cycles but I would have thought this would be preferable to a hysterectomy which has its own problems, if you can cope with the side effects for a few days every few weeks?
I am not on as high an oestrogen dose as I would like for that very reason - I don't want to take progesterone for longer and nor do I want a shorter cycle!
Oops this has been a bit of a ramble and thinking aloud while telling you my situation so hope some of it is helpful!
