AF is supposed to start the 24th.. but I have been having cramping but I cannot tell if it's from gas or something else.. I feel super bloated too.. I had pretty bad diarrhea over this last weekend but never a fever.. I didn't track my ovulation this go around so I'm going a little crazy lol Is it possible with all these different symptoms that MAYBE this could be it?? I found out within the last almost week that 3 people I know are pregnant and 2 of them are my step sisters..
