Anyone else?

I’m currently 38 weeks pregnant and have been experiencing cramping, back pain along with diarrhea for the past four days. I went in and they told me they were mild contractions but not enough for it to be active labor. I usually don’t sleep very well but these last two days I’ve been sleeping through the night (granted I can’t fall asleep until around 2 a.m) and my heartburn has pretty much gone away. Is this a sign of getting ready for labor as well? I’ve usually read the opposite, I’m just so ready to get this baby out!!
