Cant lay down keep getting dizzy

I've always gotten weird dizzy spells, like in my eyes it's hard to explain, my mom said it's probably vertigo. Today I get up with my 1 year old and as I'm preparing her food I began getting dizzy. I'm 5 weeks pregnant currently.

Once I was feeding her I got super dizzy, chest tightness, weak. I feel a little better after eating but weak. As soon as I lay down though it's like the room is spinning and my brain is spinning, I'm actually super tired because I slept bad but Everytime I try laying down im so dizzy

Dizziness making me nauseous as well
