Chances of Pregnancy?

The man I was seeing & I had sex during my fertile window (TMI-my CM was the consistency of egg-whites and there was A LOT of it), we are not TTC.

We were not using a condom (stupid drunken mistake) & I’m not on birth control, he did pull-out, but we had to keep slowing down while he was inside me bc he kept getting very close, which happened at least 3 or 4 times.

What are my chances of being pregnant from the pre-cum? I have an irregular cycle, anywhere from 29-35 days. I just need some advice/clarity on the subject.
