Still ovulating?

I got a very positive opk Thursday night and now I just got another positive and it's Sunday night. I've made sure it's not with concentrated urine for either of them. Am I still ovulating? Or possibly ovulate late? My cycles are usually between 30-32 days and I'm currently on CD18. Thursday was CD15. Any help, opinions, and/or recommendations are appreciated!! Top test was taken Thursday night and bottom one was tonight.
