38 weeks and 3 days pregnant with dizziness, nausea and vomiting!

Yesterday, I had episodes of dizziness, nausea and vomiting. Dizziness lang talaga no headache no history of migraine. Is this something that I have to worry about? I have not eaten anything unusual namn, I don't think it had something to do with my diet. The past days I believed I have not slept well enough, hindi straight 5-6 hrs yung tulog ko pero 2 days lang. Not yet in labor still at 1cm. Just worried! #1stimemom
