Extreme dizziness/lightheadedness?

I’m currently almost 5 weeks, and I woke up this morning to the room spinning.

I’m so dizzy that I’m scared to turn my head to either direction super fast because that’ll exacerbate it even more. I know dizziness is a symptom but does it get that bad?

Has anyone had it that bad and when does it get better??

I also naturally have a low BP so perhaps pregnancy is just plummeting it even lower? What can I do to manage?
