PARANOID FIRST TIME MOM

Ashleigh
Hey mommas! I had my 20 week anatomy scan and I am just really paranoid because the ultrasound technician did not really tell me ANYTHING. I had to keep asking what we were looking at and she just seemed really bored and really didn't give me much information. She said that my baby was way too curled up to get a good look her head and her brain, and to come back in 3 weeks to see if we could get a better look. 
Should I be worried?
