Starting fertility treatments!!!

Brooke
So after a talk with my Doctor & boyfriend, we discussed my options as I have PCOS & it's harder for me to ovulate on my own. We have decided to go ahead & start fertility treatment next month after a transvaginal ultrasound & some blood work.
My question is for others who have had to get fertility treatments while TTC. What should I expect?!? Will there be any physical changes? Any side effects?
Any info is appreciated. 
Thanks loves 😁😘
