My clinic have just changed their guidance - they now say to stop all progesterone supplementation at 8 weeks as they say there's no evidence it's required for any longer. At the start of my cycle, I was told to take it to 12 weeks then 1/2 dose for a further week.
I've stopped as per the new guidance but am now feeling really anxious about it. I have heard that other clinics do advise to stop earlier than 12 weeks, and I think I just need some reassurance.
