Did I ovulate yesterday?

Michelle

Hello everyone! Yesterday I took my OPK and the app said negative. I had egg white discharge and pain on the right lower belly, meaning I was probably ovulating on that side. I just took another opk, but now the line is lighter. Is it possible that I ovulated yesterday? Luckily we had sex yesterday and will do it again today, but I’m a bit confused. See pics below. Thank you!
