Fainted in bf’s bathroom

I’m still very dizzy so bare with me & thankgod for autocorrect. So I was taking a nap, I get up and go to the bathroom pretty fast too. & after I pee I start going blurry vision sweating & then I passed out fell, thought I got up but fell again. Had no control over myself. I’m 9 weeks is this something I need to call my obgyn for or do u think I just got up to fast? I couldn’t see my bf AT ALL! His face was a huge blur he said I was pale and my eyes were going back and forth trying to focus on him. Sat in the shower and I feel better now. His grandmother heard me falling and came in the room screaming for help
