Update: Nervous 13+5...Pins and needles

Tara
I am 13 weeks and 5 days and I'm feeling really nervous. I had an appointment at 8 weeks and another at 10 and the heart rate was 166-168 for both appointments. I have recently switched doctors so I didn't have a 12 week appointment. 
I have a little belly but I don't feel very pregnant. There has been no bleeding or anything like that but I'm really scared! My next appointment is on 2/3 but I am waiting on pins and needles because I'm so nervous. Ahhhhhhhh!!!!
Update: Went to the dr today and everything went well! Baby's HR is 143 and she said she could tell the gender!
