I don't believe these are pregnancy symptoms but it still has me worried

So I couldn't sleep last night just like tonight so I was up passed midnight almost 1 & had to be up by 6 this morning. I managed to get my 3 year old to take a nap (thank god!) & I took a nap while she did bc I was exhausted. But since I woke up from my nap I've been having dizzy spells, light headed ness & my vision gets a little blurry until I blink really hard. It doesn't stay gone so I have to keep doing it. Any one else experience this? Is this something I need to go to the dr for or should I see how tomorrow goes & the weekend before I make a big deal about it? TIA!
