Thanks Blue
my clinic uses estrogen tablets on medicated cycles too but different name I didn't know they were same thing -they also use Synarel from day 2 (to stop ovulation before lining is ready) and then progesterone pessaries for luteal phase after transfer.

I wanted to do medicated but at first said try natural - if my lining is not thick enough they will cancel and next cycle will do medicated

That is why I especially wanted to move on - so I know what I am up for with my lining.

Goodluck - tell me more about your clinics medicated cycle
