Ovulation thoughts

Okay so right at about 4 weeks pp I decided to start taking ovulation tests I had left before I got pregnant to see if I'm ovulating and when. ( I had to take clomid to ovulate and get pregnant to begin with) the first day I took one it was faint but could definitely see it. The next day it was pretty dark. Just wouldn't say it was dark enough to be an actual positive but it was kinda close. Then every day since then it has been practically no line so faint you can't really see it. So do you think I ovulated sometime around when I got the darker line. Or do you think I'll go back to not ovulating anymore.
