Test, or wait?

Hello,

Okay. I have two apps on my phone monitoring periods, ovulation, etc etc.

one says I'm 4 days late and one says I'm in prime ovulation. I took two ovulation test. And it says I'm not ovulating. Should I take a pregnancy and see what it says??

I'm new to this, and idk what to do.. my first child was a thrown up birth-control pill..? Situation weird.

My second was instant conception.

My OB said I'm going to have issues with this conception... so I'm just looking for opinions and advice!!
