I am on HRT and the progesterone part is Provera for 14 days every other month. I am currently having a very heavy period, sorry if TMI, and am due to start Provera in five days time. As the Provera is to induce a bleed, in order to protect the lining of my womb, do I need to take it this month as I am already having a natural bleed? TIA for any advice.
