Hi LW44 - I'm can't figure out what exactly you are taking and when??? Both Elleste duet and climaval have the same progesterone so if you struggled with the progesterone stage on the Elleste you may have the same problem with Climaval!!! It sounds as though you are still peri meno so there will still be hormone fluctuations going on until you are deeper into meno.
If you switched to the Climaval from Elleste, having only done the oestrogen section of the Elleste, then this would have delayed you withdrawal bleed as you would have ended up with 4 weeks of oestrogen only. The bleed should arrive after you have finished the progesterone phase of any HRT. After 4 weeks of oestrogen only and now on the norithersterone again, I'm not surprised you have PMT. If you felt relatively good most of the time on the Elleste Duet, why did you switch? Sadly we can't expect to feel good everyday whatever HRT we take. DG x
