Ok, when I was pregnant, I hated it when people would say things like "sorry everyone is different"; I just wanted to hear stories so that I could have an idea of what to look for, so I'll tell you mine. I just had my first daughter last February.
about two-three weeks before, i started contracting more frequently and more painfully than normal; probably just braxton-hicks. I started walking a lot, shopping a lot (so that I could stay on my feet as much as possible), and I got one of those big balance balls. I sat on that ball for like 3 days straight, rocking back and forth--I would almost swear that's what finally got labor going, but maybe it was just a coincidence. Also, I had sex the night before I went into labor, and by 11 am I was in labor. My water never "broke". I had no big gush. I thought it broke one night while I was on the ball, and I even went to the hospital, but they told me i just peed my pants (I still don't believe that--it definitely felt like it was coming out of the vagina hole).
Anyway, back to how I felt in the week leading up to labor. I felt sick, like I had the flu or something about three days before I went into labor. Earlier in the week, and maybe even for a couple of weeks, I felt SO hot that I couldn't stand it. I gave birth during that huge snow storm in February, and the only way I could get relief from how hot I was, was to go outside in shorts and a tank top and just stand there with my arms spread out for a few minutes. It was heaven...and everyone else would be freezing thinking I was crazy. I got really swollen the week of, and gained 10 pounds (I assume in water weight, because my foot and ankles looked like professor klumps). I did start having the mucous stuff come out about two days before labor. It wasnt one big clump, but just chunks of gooey stuff randomly for like two days. Then the morning I went into labor, I got out of bed around 11am, and when i put my legs over the bed I felt a little rip or tear or pop. not sure how to describe that feeling, but it wasnt painful or anything. i could just tell that something happened. i went to the bathroom and i had a little more leaking--but i thought maybe i just "peed my pants" again. Oh, I should mention, this happened like a day after the first time they told me i peed my pants. I think they were wrong, because they almost sent me home the second time too---even though I was definitely in labor that time. It was for the same reason, they said my water didnt break--but I must just have weird fluid that doesnt turn the testing stick the right color. then that was it, i was in labor.
