Ovulation help

first time mom

So I’ve been talking ovulation test for a little over a week. Day 1 & 2 I got negatives but now I’m I’m getting high (6 days in a row), what is going on. I’m so confused. Have I ovulated or not?? Last cycle I ovulated day 17 of the cycle and today Is day 18 so I’m thinking it’s still possible. Our bodies are so complex.,
