So, normally I am a txtbook 28 day cycle. Oing on CD12 AF on CD28 (16DPO) so my luteal phase is normally 16 day right? Ok ...

This month, I O'd cd15/16 so therefore this cycle My period wont be due until Sat 25th Sept (CD31, 16DPO) is that right? Or am I calculating this wrong?

After my lap done cd19 - should i still expect my period to arrive as per the norm?
