Can’t stop passing out :/

I’m 17 weeks pregnant and have been almost passing out for a few weeks now I’d say since I was 11 weeks. Ever since I got my blood drawn two weeks ago and actually fainted, I’ve been fainting more. I’m in bed most of the day and whenever I go to cook or do something I can’t stand for more than 2 mins without running back to the room to lay down. I cry because the pain is awful and I’m sooooo tired of feeling like this i want to feel good so I can get things done and do things before I have the baby. Anyone have any remedies or tips for this?? I really need it it’s a EVERY DAY thing
