33 weeks pregnant tomorrow and feeling off

Elizabeth

I'll be 33 weeks pregnant tomorrow but today I feel weird. I don't deal with sweeping much but today my face feels super heavy and puffy around my eyes, almost like I was crying all night, and and my feet were swollen. My feet have gone down some since I propped them up but I swear my face feels worse. My grandma says she can only see slight swelling there though. I've had diarrhea two or three times today and my stomach is a bit upset. I don't know if this is related or not (probably not because its not very severe) but I have a very slight headache behind my eyes and I've had an air bubble type pressure under the right side if my ribs for a week now. My fiance thinks I should go to the hospital but I don't want to rush in unless i need to. Can someone give me some advice? I don't feel like I'm dying or anything
