I'm currently 15 weeks and 1 day, since midday Saturday I have been experiencing pain in my lower belly. Sometimes it's to one side or the other, sometimes it all over the lower belly. The pain has been pretty consistent since Saturday. I will say that is isn't severe, just concerning and really uncomfortable and I am not experiencing any other symptoms or bleeding. I'm not sure if it is just things stretching and getting moved around or if there's a more serious issue. Any advice?
