Scared!!! 16 weeks!!

Ashley

Hi ladies, so i was just waking up and had to use the bathroom really bad. As i was getting up to use the bathroom i was coughing and i heard a pop. Like something down there broke or snapped, i felt slight pressure in my ribcage but that went away after a few seconds, i haven't had any discharge, blood or pain. But im so scared of what that was. Popping past 30 weeks is normal, but not 16. Please help!!!!
