5 weeks or so ultrasound?

Brooks
Hey ladies, just had my first wellness visit today along with an ultrasound to confirm my due date. They figured out I was 7 weeks but I had told them that my menstrual cycle isn't the normal 28days, more like 36, which is why she wanted to check and make sure. Sure enough, there's barely anything there, though the tech said on the right side is where it looks like it's forming. Is this normal for it to look this way or am I less than 5 weeks? I have to go in for another ultrasound next Friday.
