this can't be normal

Me
I am 34 weeks pregnant and I am in so much pain that I don't even remember what feeling normal felt like. Last week the pains started. My entire back hurts, my knees hurt, I am short of breath. I get this light dull headaches. If I walk for 2 blocks that walk messes me up so much. I am catching leg cramps, hands cramp, feet cramp. I went to the doctor and he said all is normal. I might just be dehydrated which I have started to triple up my water in take. I hate taking pain medicine but I have been taking a Tylenol a night for some relief. I just can't believe this is "normal" especially if I have 6 weeks to go there is no indication that he is coming early. If others feel the same was there something behind it?!? My doctor won't schedule a csection till I am 39 weeks so it's not like I can go earlier. I don't have that luck. 😩😫 thanks in advance to anyone who can post some input.
