Plan B and ovulation

Help! My boyfriend and I had unprotected sex yesterday and I took a plan b pill about three hours after having sex. We then had unprotected sex again three hours after taking the pill (I realize it wasn’t very smart). He came in me both times. My period had just ended the day before we had sex. Anyways today, I’m having cramping on one side like when I’m ovulating (always happens) and I had some stringy/egg white like discharge (always happens when I’m ovulating as well). Could this mean I ovulated? Or could this be effects of plan B?

Edit: the cramping is just on one side which is what’s concerning me more. I thought the plan B cramps would just be generalized
