Way too much Dizziness!!

I'm 4 in the half months preggers and I've been experiencing way too much dizziness, to the point where I have to hold on to items around me to make it the the bathroom, as soon as I lay on my back my world spins, laying on either side doesn't make any differences. I eat and drink and take prenatal/ iron and folic acid on a daily but I'm also severely anemia!! Wondering if anyone have any suggestions!! 😢 I just wanna feel normal!
