Is it possible to ovulate right after period?

I always feel when I ovulate because it is painful for me and uncomfortable. It usually lasts a whole day. Well this month right when I finished my period maybe like a day later I started having really bad left ovary pain just like when I ovulate but this time it was more painful 😣 it lasted a whole day. I’ve never felt ovulation this early it’s usually in the middle of my cycle just wondering if this is ovulation pain or maybe a possible cyst? I made an appointment at my GYN for this coming week and I think I’m also getting a UTI 😩 also I took plan b the week before my period started so I’m wondering if this has anything to do with it
