Follicle Ultrasound

I went in this morning to had a transvaginal ultrasound to check to see if I had any follicles. I had one big perfect follicle in my left ovary! It measured around 20mm. The nurse gave me the Ovidrel trigger shot... we shall see if it works! I go Monday for my regular doctor checkup and then Friday for bloodwork to check my progesterone level to see if an egg actually released.
