HELP ME, PLEASE!!!!

Kennedy
Alright Saturday 28th I noticed my CM was getting stretchy and milky, but I was out of town. Sun my CM is still stretchy and egg white/milky DH ejaculated in me that night, are we too late or is there a chance I could get pregnant. DH Also evacuated in me Monday night. Just confused on when I should test now and if I was ovulating then or not? Sorry if this is confusing. Today is Wed the 1st and I'm having a sharp/pinching pain in my lower right/middle abdomen below my belly button. What is this pain? Some articles say it's ovulation, some say it's implantation?
