Pregnant after pull out method? Is it possible?

So I am ovulating (took the clear blue advanced test and it said peak on the 19th) had sex multiple times a day on the 12th-16th, 19th, 20th, and 21st (this morning and probably will tonight). My boyfriend pulled out each time. But....FYI TMI ahead....I did go to wipe the cum off my stomach and he inserted that finger with cum all over it in my vagina yesterday and this morning....sorry for the graphics lol. So I am asking has anyone gotten pregnant like this or from pre-cum? We recently had a miscarriage last month and we are both hesitant on ttc right away again.
