Did you use sneakpeak?? Was it accurate??

Just found out I’m pregnant yesterday and I’m over the moon excited since me and my boyfriend have been trying on and off for almost a year. Based on my last period I would be 4 weeks today. I always thought I wanted another boy, which I would, but after trying for what felt like forever, I just can’t wait to find out the gender and would be happy with boy or girl. Question is, have any of you mamas used sneak peak or another form of lab test?? Do you recommend? Was it accurate? How far along were you when you took it? The idea of finding out the sex within the next few weeks makes me really excited but I also want real life experiences and thoughts from others before doing so.
