pickle Your GP sounds very confused!
(As well as telling you incorrect stuff.)
Maybe do your own reading around HRT because I get the impression you aren't too sure how it works?
There are 2 main types of HRT which come in formulas for women in peri or post men. This includes patches, tablets and gel (with a separate progestogen.)
1 Sequential where you have a bleed. This is for women who are not yet 12 months with no period
2 Continuous where women have not have a period for 12 months
Sequential means you use estrogen and a progestogen on a monthly basis - so, estrogen daily and a progestogen for 12 days each month. 3 days after the end of progestogen each month you have a withdrawal bleed. This is not a period, it's to clear the womb lining to stop it over growing.
Continuous types- estrogen AND a progestogen EVERY day. Using progestogen daily keeps the womb lining thin. You would not have a withdrawal bleed.
Women do not have to use continuous ever if they prefer not to (some women can't tolerate daily progestogens.)
There are patches that are sequential and patches that are continuous. Same for pills.
With gel, you can use it either way- gel daily but a progestogen either 12 days a month or every day . So it's for anyone- peri meno or post meno.
