Multiple ovulation days??

Is it even possible to have multiple days of ovulation? Using the cheap ovulation tests has always been spot on for me but in the past two months it seems that I have two or three “peak” days where the test line is much darker than the control line. I know there are high fertility days... so are my levels just extremely high or am I really having multiple ovulation days? I didn’t think that was possible. Yesterday’s is on top today on bottom. Yes I realize they are dry now but they’re exactly as they were when I took them. Both lines are darker...?
