I am 39 weeks 2 days and All day on and off I've had stomach tightening and shortness of breath. . Now I'm getting the same feeling plus a sharp pain shooting down my leg. No real bad back pains so idk if I should worry. On Tuesday my midwife said i could be having early labor. . I've been having lots of contractions but they don't hurt at all. Just tightness. What are your thoughts?
