Contractions like every 8-10 min baby is moving all around. The contractions last 30-45 seconds. Dilated 2 cm 60% effaced this morning at appt. After work took a 2.5 mile walk.Could it be the start of labor? I know 8-10 min is not close enough to go in . These contractions start in my back and make my entire tummy very tight cause me to breathe slightly heavier, not teribbly painfull just strong
