What do you guys think?

Ok so, my bf has been sayin for the past few days that it "feels different" when we have sex. He said its really soft and squishy, so I decided I'd check my cervix & its not there! I can't reach it and its usually low at this point I'm kinda freaking out cause i have 4 days left in my cycle and i don't wanna test yet cause i don't wanna get a negative... 😣😣😣 guess i have no other choice but to wait & see if my period shows up
