late ovulation low progesterone

[tarka123]

I’ve just done my first round of OI on letrozole for PCOS 2.5mg OD. Was scanned once and no dominant follicles. Told to keep having sex and on day 18 tested with Mira machine. Had big LH surge and both oestrogen and progesterone were higher than previously. Did d21 progesterone blood test today (too early and will go again) but level was below 1. Has anyone else had this and then tested later and had a positive progesterone rise?

Not everyone has a 28 day cycle -could be your cycle is longer so need to have blood checked at a later date

Good luck for the future
