Please no rude comments the pills is confusing for me

So I’ve been on the pill for a month. This is my second month on the pill.

I haven’t been taking my pill at the exact time because I’m really forgetful but I have been taking it ever day

So Saturday the 23rd of November I had sex protected and then unprotected and my boyfriend pulled out and didn’t cum. After that I started bleeding for a day like my period because my periods ended on the 22nd.

On Wednesday the 27th my boyfriend and I had unprotected sex where he pulled out like 5 times.

I took a plan B pill on the 28th

What are my chances of pregnancy.

Please help. No one has explained the pill properly and I’ve been googling it but I’ve been getting confused. Please please help.
