Extreme abdominal cramping that comes and goes. It’s a sharp pain that lasts for 30 seconds maybe a little long then goes away and comes back sometime later. I’m unsure if it’s gas pain. TMI I’ve had 3 bowel movements today but still feel like I need to go and burping a lot. Is this just gas pains or should I go to the hospital. I’m super unsure and with covid going around in trying to avoid hospitals but want to make sure my baby is ok.
