Hi everyone, this is my first pregnancy and im just really not sure that when my tummy aches i can't tell if its just the baby kicking or im actually having contractions, i dont know the difference between the two- are they supposed to feel the same or are they in different locations, how can you tell if the baby's just being active or your actually having your contractions and your nearing your labor?
