Follicle Size

Ro

I am undergoing fertility testing. Last week at my Day 3 ultrasound, they said they saw a 32mm follicle that could be a cyst or carried over from last cycle. The nurse called today and said my blood work looks good , no red flags, but they want to do another ultrasound next week to check the follicle again since it is large. I should be ovulating next week and want to TTC but the nurse told me to hold off for now. I am surprised I can't continue to TTC. I hate to have to wait another month! Anyone have similar experience?
