Hi so I had a positive test on Saturday 1st Feb late evening and BD Sunday afternoon is there a chance for pregnancy?

My <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> on here says I ovulated on the 4th Feb? But I think it’s wrong considering my peak test Saturday 1st?

But my other app says I ovulated on the 2nd Feb?

🤞Which one is correct? 🤞

Please someone help me understand cause I’m so confused😂
