A couple of things:
I've found out that 'tds' is the doctor talk for three times a day! I contacted the gynae to ask if it was still this dose of Provera on low progesterone and he said yes

( but made no comment about my question if I only wanted to go 2 months. He quite clearly said '....I would therefore recommend you take the dosage ie 3 times a day for 14 days.....this should be taken at three monthly intervals'. He also said a routine scan would not be necessary as long as I take the medication as advised and report any abnormal bleeding.
My other thing is that this Friday just past, I switched to this new long cycle routine and started the Estrodot 25 mcg patch to replace the evorel conti 50 mcg that I'd been using up till that very changover (albeit just under half a patch at a time). So basically just a small increase in the oestrogen amount. I can't say I'm progesterone intolerant (I don't know what the criteria for that is) but each time I've tried hrt I've felt a surge of feeling v good and then slowly headaches take over and with the evorel I had a constant feeling of irritability, almost anger. I found this outweighed the good feeling hence the switch.
When I started the Estradot within a day I felt my head was clearer, I felt lighter and not so irritable (but hey I'm a bit of a cranky old thing at the best of times!) But last night a headache came on! I'm so disappointed, just the same headache as I had with the conti stuff. So maybe it wasn't the progesterone causing it and now I'm wondering if I should never have started playing around with it and have set myself up for high dose progesterone which might make me feel terrible! Sorry ladies, off loading here - this all takes so much time aaagh! I feel stuck between a hard rock and a stone.
