39 weeks pregnant please help!?

Hello ladies, well im almost 39 weeks. And this morning while I was eating breakfast, I got a major dizzy spell. I still feel a little wierd but not dizzy. I have been testd for preeclampsia and I dont have it. But I know it can come later in pregnancy. So do you think im o.k? I have been very busy lately. Do you think if I take it easy today it will go away? thanks ladies.
