Zika Virus

Mi
So I just got back from a trip to Mexico and i didn't find out about the zika virus until a few days into my vacation and we decided to come home early because of it..I called my dr when I got back to ask if I can come in to be seen because I was worried about it..they didn't seem to worried said that I can come if I want next week to do an ultrasound..I'm a bit confused as to why they wouldn't want to see me right away to get a blood test to at least rule it out? Am I being ridiculous and just trust my dr or call them back and ask for a blood test! Help!😩
