LH still high

On CD 19 I got a high and later that day got my peak. It’s been high ever since, not as high as the peak but still high and it’s currently CD 23. I also got a high on CD 10 but thought it wasn’t ovulation but now I’m wondering if CD 10 was really ovulation and now I’m getting all the positive LH strips because I’m pregnant...I don’t have any pregnancy test to take so I haven’t tested but thinking I should go buy some. I had really intense pain on CD 17 which I thought was the start of ovulation but I guess it could’ve been implantation. 🤔
