So I read that sometimes you feel real contractions down your legs. I just felt a tightening on the backside of my right thigh but not in my tummy area. I read that it's a contraction but it stems from your tummy down to your legs, but I didn't feel anything in my tummy area. Could what I felt in my thigh be a real contraction or the baby just hitting a nerve. I'm 39 weeks & 5 days.
