NEED SOME ADVICE!! HELP LADIES!!

Ovulation 10th-16th just going off of glow calendar had sex 13th-15th. When I go to bathroom just today and I wipe it’s a light pink kind of brownish tint. I have never had IB so I’m not sure what to expect I have had slight lower abdomen cramps on the right side but nothing serious and it comes and goes. It’s 10 days until AF is supposed to arrive. What do you guys think? I also have never had any bleeding between cycles at all!!
