need some help

Okay so I wanted to know what are some of your insights. So according to glow my fertile week was this week and I ovulate this Sunday. So I BD 2/20, 2/21 and 2/23 and mignight. I took my ovulation kit on Wednesday 2/21 and got a negative and then took it 2/22 and got a positive and took it today and got a positive too. I also experienced on thrusday some mild pain on my right side and today a bit paid as well. I'm trying not to stress because it will make things worse. I guess what I'm trying to ask is these days I had intercourse is there a good chance that I could be pregnant next month? I mean from getting a positive ovulation test thrusday and BD on midnight was the sperm still able to get to the egg? and how do you know if the egg fertilized? fertilize
