When did I ovulate??? HELP! 🤔🤔🤔

Courtney

So I know a few ppl said they think 2nd and 3rd last opk's looked negative.. but that's the darkest I've ever gotten off a dollar store cheapie. When would I say I ovulated? The surge is completely gone now, my last test was this morning. Would I be 1dpo today? Also how good are my chances to conceive? I bd'd last night and every other day before that.

Thanks!
