Could be your iron levels need checked xx
In the beginning of my first pregnancy I fainted/passed out a lot. I also realized coffee made it worse for me personally. But they said to me when it was an issue it’s normal. But if it’s happening far too much. Then you should tell them it’s affecting your day to even do little things.
Maybe make sure you drink at least a gallon of water a day
I don’t think passing out is normal. I’d definitely get that checked out
