BG has answered the question really well. I'm currently pregnant from a HRT FET. The reason I had to have a medicated cycle was due to my cycles being all over the shot/non-existant (PCOS). So rather than risk waiting months for me to ovulate I took HRT and then progesterone pessaries.

Ruth - I kept up the pessaries until I was 10 weeks pregnant. My FS and OB said there is not any proven data that shows taking it for any longer assists the pregnancy. By the time you are 10 weeks the placenta has taken over most of the hormone control.

Best of luck.
