I'm currently 39 weeks and experiencing mentral type cramping that is constant but every 18 minutes I'm getting stronger sharp cramps that only last about 30 seconds along with belly tightness. Mild lower back pain and lingering pain in my hips to love handles. I've been also experiencing major pressure down below and the urge to have a bowel movement but can't.. Also bad heartburn. Just not sure if this could be the start of active labor. I live 45 min away from the hospital so I kinda wanna be ready to leave if I have to.
