Scared to hear results..

So I have been off of birth control for over a year now. My husband and I haven't been trying really hard mainly because we don't know when to time intercourse due to my irregular periods. I had some ovulation blood tests done back in November, that showed I wasn't ovulating. So we just kind of let it go because I wasn't ready to start Clomid. I just went back to a different dr (wasn't happy with the other) because I'm sick of not knowing when my period is going to be and not knowing when to have sex. He was great but thinks I may have PCOS so we did blood work and I'm going in for the ultrasound next week. I'm really nervous for the results, does anyone have experience with this that can calm my nerves? I've been stressing so much over it.
