Being sent to Genetics

Anyone have to be sent to genetics? My cystic fibrosis screening came back positive that I am a carrier so now my husband has to be tested and my OB wants to send me to a specialist to do a genetic work up. Anyone else in a similar situation? All my friends say their test was negative. I don't know what to expect at genetics. This is my first baby and we had trouble getting pregnant so I'm just feeling a little stressed and nervous.
