OPK confusion and the next step?

Kat

So I have had many almost positives but just barely not. But now I’m getting really negative opks. Should I just assume that my almost positives are the best surge I’m going to get and hope it was enough, or should I keep testing until I get that positive? I’ve had an irregular cycle here and there (ironically conceived both of my living children during cycles where I ovulated on like cd 45) so it wouldn’t be totally nuts. I’m just annoyed that I don’t totally know what’s going on. And I’m worried if I don’t test we won’t bd at the right time. Opk pics included.
