How likely is it that I’m pregnant?

I’m 24 and I’ve been taking pills for almost a year now to manage my pcos symptoms. I started my period on 24th and ended on 28th July. I start my period on 4th day of placebo pills. I started my new pack of pills 2 days later than usual and had unprotected sex on 30th and he came in me. I was already on day 3 of my new pack that day. Given everything how likely is it that I might get pregnant?

Ps- Please don’t be rude I totally forgot that I started new pack 2 days later than I was supposed to.
