Blacked out in the shower

Just when I feel like things are uneventful and going well, I blacked out in the shower this am. I felt it coming on so I sat down and put my head against the wall, so luckily I didn’t hurt myself. Now I have a horrid headache...and get to take a trip to the ER :(. Just wondering what could’ve caused it...maybe low blood pressure??
