When to test and when you’re out.

So I ovulated on the 23rd, meaning I would be 12 DPO? Right?

I tested today and felt as if I seen a line but my line eyes it may have not been there.

Is there anyone that didn’t get a positive till later on or should I count myself out?

When I press on my boobs they are sore but it’s nothing crazy, I feel if I have symptoms I should be getting a dark test line.

Just not knowing what to do it if I should test again?
