Ovulation Question

Question. I have been using opk testing sticks. I had to give in. Ovia wasn’t telling me my ovulation day. I actually am using 3 different apps to track it, and now finally it is telling me I should ovulate today? I took a test around 10:30 last night and it was positive.

I should ovulate today or tomorrow then?

Next question is has anyone gotten pregnant only having sex twice in their fertile window then? It was the first day and and yesterday. Trying not to “plan” so today may or may not happen with doing the deed 😂.
