Follicle study. Tensed because of this.

Hi, I am 27yr old planning for pregnancy, I am type 2 diabetic and also have PCOS, I had been advised to lower my hba1c and try for pregnancy, I took almost 4 months of time and lowered my sugar and when it is in control, I started the follicular scan in which my doctor suggested me that my follicles are not growing, I took letroz 2.5mg for 5 days and menopur 75iu and did the scan, my follicle size grown to 10, 8.8 and ET size 6.3mm TL, my doctor suggested me to take menupur injection for 3 days straight and again scan, now the left ovary shows 14*13*12 and ET size 6.6mm TL, now my doctor suggested me to take menupur for 2 more days and then scan again, as I m diabetic my doctr is not suggesting me to take any other medicine as it may harm my health, is the chances of getting pregnant is high in my scenario with these medication, will my follicles grow and will I get ovulate, I m getting tensed because of this.
