Should I get another u/s??

Was told GIRL after two different u/s tech took 30 minutes trying to get a good angle to see. Their conclusion was "we don't see a scrotum hanging down or any boy parts sticking out and we would've by now". Baby had its legs tightly crossed and umbilical cord in the way as well. Just wondering if I should plan on buying some pink or wait a little bit. Opinions and insight welcome!!
