need some advice.

👪
I'm a FTM and I'm 37+6. I feel SO… not right. I'm not having contractions and my water hasn't broke but I feel SOOOO light headed, out of bodyish, achey, a lot of pelvic pressure when I'm standing, my face feels so hot like I'm sitting in front of a fire. I don't know if I'm just really tired (not sure why I'd be tired I spent all day just relaxing and even took an hour long nap) or if I'm in labor. I know labor can be different for everyone but I don't know if I should tell DH and have him take me to L&D or if I should just try to get some sleep and see how I feel or wait to see if contractions start.
