Girls, week 34 and 2 days. All day today strange sensations. Belly hurts like it's about to start period and this pain radiates into legs and legs begin to feel unpleasant tingling, then releases. But belly is not stony. Sometimes I feel pain in my lower back, even when lying on my side. The baby is so active. Are these training contractions or something?
