When did i ovulate?

I'm new to this. I had my first positive opk on Thursday and Friday they were still positive. Saturday the lines were dark but not exactly the same colour so negative I'm guessing. In your opinion when did I most likely ovulate? I had intercourse Wednesday, Thursday, Friday, Saturday and today (sun). However I don't think he actually ejaculated in me because nothing leaked out at all, although he said he did. Do you think I've done enough ? I'm panicking about today the most... I had egg white discharge this morning and I don't think he even ejaculated inside 😩
