Ouch

I had my ultrasound this morning. It's cycle day 13. I had 2 follicles - one is at 22 and the other is at 16. The nurse said the 16 might grow enough to be released. Tonight I have to give myself a trigger shot of Ovidrel at 9pm. Then I'll wait until Thursday for my IUI. I have had bad ovulation pain all day - hopefully both of the follicles will be released.
