Need advice!

Hey y'all, so I'm on CD 38 and still no period. I was supposed to start Aug. 23 I think. I've taken tests and all were negative. Now Glow is telling me to get ovulation tests. Is it possible for me to be pregnant? And it not is it possible to ovulate when I didn't have a period? I'm going to the OBGYN tomorrow maybe they'll end up saying I'm pregnant! Any advice is appreciated!! :)
