I think the confusion for the two of you arises because you both still have a womb right?
That needs to be protected, so you need progesterone to ensure that the oestrogen they give you to replace your ovary oestrogen doesn't thicken the womb lining. Women who have had their wombs removed don't have to use progesterone so there is no choice they get given oestrogen only.
Women who have wombs have to have both hormones but even post meno it is a choice really between a "bleed" or "non-bleed" regime. The conti regime is supposed to be the non-bleed, the sequi regime includes a bleed. The idea behind a conti is that the progesterone and the oestrogen are balanced totally so the lining doesn't thicken nor is there a bleed. Sometimes it is quite hard to achieve and spotting occurs. The sequi means that there will definitely be a bleed. Most GP's suggest that women who are post meno don't want to be bothered with a bleed so prescribe conti but if you are like me and cannot tolerate continuous progesterone which makes us feel ill, it just doesnt work for us. In that case, we chose to have a sequential regime and have a bleed because it suits us better and we have to just put up with the bleed!
Bet that's as clear as mud huh!!!
