Feeling extremely loopy and out of it

I’m 5 weeks 4 days…today I have felt queezy and beyond exhausted. I didnt eat anything but a few chips bc its all I could handle. This evening around 7 i started to feel dizzy, the room was moving in circles and I couldnt even walk to the couch without the room spinning. Is my blood pressure/sugar low? Somebody please give me advice, I never had this feeling with my first born. Im kinda scared at this point but google says to eat fruit if its low so im doing that at the moment.
