FTM. 31 weeks.

So I just figured I would ask on here since so may of you moms have done this before. For a few days now I am getting the really bad pain in my lower back. My blood pressure keeps dropping on and off. And now as of today I feel so off I can’t seem to focus on anything. I’m getting a migraine now. And keep having the constant feeling of having to use the restroom( which I know is normal) but every time I go I’m not actually peeing much. And I’m now very thirsty, keep drinking water but it’s just not going away. Lastly the part that feels weird today is that she doesn’t seem as active as she usually is. Am I just overreacting and this is all normal pregnancy stuff??
