advice needed!

Hi! So yesterday I had sex for the first time. My period began on the 15th of febuary and finished 19
I had sex yesterday the 20th
It was my first time
I have been on the pill for 3 months now
We had sex 4 times
Once with the condom and the rest
Without
But we did the pull out method
He pulled out correctly (he came in his hands each time)
Can you guys please help me with advice so I can sleep at night!
What do you think my chances of getting pregnant are?
Please be honest and as helpful as possible!
Thank you
