38wks 2days No Signs Of Labor!

I'm 38wks 2days and had my 1st cervical check at 37 weeks, Dr told me I'm not dialated at all! So he told me to walk alot and have sex. Went again yesterday tried the sex thing even though it was so uncomfortable and I've been super active since the begining of my pregnancy. He told me the same thing that I'm not dialated at all, he didn't mention if I'm effaced or not. Well I'm super dissapointed I don't know what I'm doing wrong?? I'm still working full time but my body can't do this any longer. I'm exhausted and can barely walk with all this weight and my pelvic bone hurting like hell!
