Help me figure this out!!!!

Okay! So ladies, I need help somewhat figuring stuff out.

My cycles are usually anywhere from 26-32days.

I BD on cycle day 17 this month, 10/9. And that was it.

I remember that was a Friday and I remember thinking my cm was very egg white like and a lot for the rest of that weekend.

On 10/22 I have light bleeding and then took a test and had a positive pregnancy test...not blazing but definitely positive.

When do we think I ovulated? And do you think the light bleeding...only very minimal after one or two wipes, was that implantation bleeding?

Really I’m trying to figure out somewhat when I ovulated.

Thank you!!
