Fertility after stopping meds

I have done 3 cycles of clomid and 1 cycle of letrozole (femara) with my infertility specialist. I took a month off, saw a reproductive endocrinologist, and will be starting letrozole again this month with closer observation on my thyroid ( I'm hypo with "lean" pcos). So far, my cycle seems pretty standard. Ewcm when I normally get it (days 14-16ish) but I'm interested to see when I will start my period or if I'll have to get a jump start with that. On meds, my cycle is 28 days. Before meds, it was 32-35 days. What did your cycle do on a break from fertility medications and treatment??
