I was the same way at my first appt only cuz it took me so long to get pregnant and when the doctor checked my heart beat she laughed and asked if i was nervous. Everything turned out fine and im sure the everything will be fine with you. Good luck.
I was so scared my first app bc for some reason i thought nothing would show up on the ultrasound but of course something did and then i just couldnt quit smiling the whole rest of the app haha. I cant wait for my next app its driving me crazy!!
How far along will you be? If your not at least 12-13 weeks you may not hear the heart with a Doppler. But if you have a sono you will good luck I'm sure everything is just perfect
You will be fine just relax and enjoy your pregnancy! It's nerve wracking. But when you hear your baby it's unreal
