Fertility Dr tomorrow!

Brandy • Married, hairstylist, mom of 3!
Got a call back today and set an appointment for tomorrow at 1!!! I'm kind of excited and nervous. I was lucky they had a cancellation because the next new patient appointment they had available wasn't for 6 weeks! Hopefully this Dr will go ahead and set me up for a follicle scan and 21 day lab. What day do they normally do the follicle scan?
