Is this normal...?

I feel like I’m just being a wimp or something but I’m seriously done with being pregnant... I went to my OB the other day and she said I was measuring 2 1/2 weeks ahead.. which would make it 35 Weeks Monday. I’m in SO much pain I don’t even know how to express it with words.. my back feels like I threw it out I’m sitting here crying just because I made dinner and was walking around the kitchen.. my belly has dropped significantly.. Everything hurts so damn bad.. is this normal or should I seek medical help?
