2 days after period (pregnancy chance)

Hey everyone,
My husband and I were planning to be TTC around April-august, but this weekend 2 days after my period he didn't pull out.
It's not a huge deal if I get pregnant, because we were planning on doing so this spring/summer, but I want to know the chances.
On one hand I see so many women struggling with TTC and that it takes much longer, on the other I see all it takes is one time (I had my first early on in life--but it was more around the ovulation days).
So 2 days after my period, what is the likelihood of getting pregnant?
(I haven't been on BC in a year--- hormonal balance, etc)
