37 WEEKS PREGNANT... LABOR SIGNS??

Like it says in the title .. I'm 37 weeks .. the last couple days .. I have been so constipated & my ankles (aren't swollen) but they hurt so bad .. it hurts to walk. I've been rolling them and trying to crack them.. it doesn't help. It hurts pretty bad to where I don't even want to walk... I just want to sit here so it doesn't hurt. I've been very very crampy .... like period cramps .. and my back hurts so bad. Is any of this signs of labor ? Last week I was 2cm & 70 % effaced... I'm hoping to have a speedy delivery and recovery. Hopefully soon.
