Pre labor symptoms?

For those of you who have given birth already, how did you feel the few days leading up to labor? Did you have any unusual symptoms? I am 39w2d and for the last week and a half have had lots of period like cramping, Braxton hicks, hip pain, lightening crotch, etc. I figured that was all related to baby dropping. But yesterday afternoon I started feeling dizzy and later in the evening nauseous too. Have also felt like my body keeps trying to poop even though I don't have to (tmi). I'm sure I'm probably looking into every symptom but I am so anxious to meet my little man!
