Biggest Scare of my Life

I had my 2nd of many prenatal visits today. Dean couldn't get off work to go so I made this trip North by myself. I have a really nice nurse practitioner named Mrs. Roohr. Because we have wonderful government/military, I don't get to see a doctor unless I'm dying and oh here's the kicker: I'll meet the doctor that will deliver my baby for the first time, the day I deliver. I wasn't supposed to get an ultrasound this appointment, it was just for me to get weighed and listen to the baby on the Doppler. I laid back on the the table was ready to hear my baby but all I heard was a gargling sound but I thought it was the bacon, egg, and cheese bagel from McDonald's I scarfed down in the car right before I went in. (Side note: McDonald's breakfast is my weakness.) I was kind of scared when I didn't hear anything for a good minute. Then she asked me the scary question, "Have you had any cramping or bleeding?" There was only one reason I thought she would be asking that question, maybe I had lost the baby. After about 10 seconds of silent panic she asking if I could hear the bubbling noise. It turns out the baby was swimming away from the Doppler and that was the noise I heard in the beginning. She took me to the ultrasound room to do a quick scan to get a fetal heartbeat count. I was so happy to my my little peanut squirming around on the screen. Mrs. Roohr still had trouble catching the little bugger then, but after about 6 tries we finally count a count: 150 bpm! She said that's really good and it's good that the baby is active.
she also said I need to gain a few more pounds before my next visit, like I really need a reason to eat more food. My next appointment is July 19th and we'll find out the sex then... any predictions?
