i have 22 days left or sooner and im the type to feel a pain or feel sick n hold off on seeing a doc as long as possible. well, i get im pregnant n isee my midwife but i had contractions earlier that made me wanna cry (not close together nor lasted long) but my bf ask if i needed to go to the hospital n i said no. bc i dont wanna drive little over an hour to the hospital just to be sent home, so i guess my question is what are signs (how far apart or how long should contractions be) or other labor signs so i dont end up not going in when i probably should?
