My doctor is a brat!

Xanthia
Back in December I had a miscarriage, I am now 17 weeks and due Christmas Day. Yesterday I started spotting a tiny bit but because of my past miscarriage I was extremely worried and when I called the doctors office they told me to come in ASAP for an ultrasound. I went in and everything checked out perfectly with the baby. My doctor thinks I got a small tear in my cervix that caused the bleeding. 
Anyhow. During the ultrasound the doctor was able to see the gender of the baby and I didn't catch it (cause I obviously wasn't paying attention to that). Our official anatomy ultrasound is in two weeks on the 31st and the doctor said he won't tell me til then!! He's such a brat!! I want to know what this baby is NOW! Haha.
