What is the likely hood of conceiving?

Kayla

Obviously, red is period. The days with the green are unprotected sex and blue is my fertile window. I confirmed ovulation April 5th with an opk. Could I have conceived? My cycle is 30 days long every month.

I’m not trying for a baby, I would prefer not to have another. My fertile window started 3 days after I had unprotected sex. Can anyone give me any insight on how likely I could be pregnant?
