Please Help!!

Nakia

I had my 2nd prenatal appointment yesterday! I'm currently 14 weeks and 5 days. Dr could not get the heartbeat with the doppler....but did not schedule ultrasound until May 2nd......a whole month from now! She said she wasn't worried as things looked perfectly fine on March 14th when I had the translucency ultrasound. Needless to say I am freaking out. This is my 1st child and I'm concerned.
