When to test

So, I have multiple period tracking apps (I know, I’m crazy) and they don’t all match up for when my period will start. They are within like a 3-4 day period. I just got off BC in January so I don’t think I’ve had enough cycles for the apps (or myself) to really know my cycle. However, I’ve been tracking my CM and taking OPKs to figure out when I ovulate. With that being said, when should I take a pregnancy test? 2 weeks after I ovulated? Or do I need to wait a little longer? I’m only 5dpo now so clearly way too early to test. But, just curious when I should.
