i have been having a fluttering feeling in my stomach that feels like baby movement for about the past two weeks. my period is supposed to start on the 14th and i have been having like period cramps almost in the my lower stomach where the fluttering is. i know it is not gas. i have two children already and had a tubal ligation 8 years ago so i know my chances of becoming pregnant are very slim. could you possibly help me understand what is going on inside me??
