Last night I started having Braxton Hicks that were fairly close together. They aren't consistent yet, but they are getting more frequent then they have been before. I've had a dull back ache for the past several hours, and on and off since 8pm yesterday. Does this mean I might be close to labor? I haven't been checked yet for effacement or dilation, so I have no idea if that is anywhere close to being ready for delivery. First baby, and want to know if I should be timing the contractions? I'm just so lost!

37-ish weeks or so.
