Is she going to be pregnant?

March 9 was when I have an intercourse with my girlfriend without any protection, I only put it and try to push all through not knowing it was the cervix, only thrusted 5 times and finished it with my hand, used the withdrawal method, the sperm being on her stomach. Exactly 24 hours later she take the yuzpe method (4 pills then another 4 pills after 12 hours). She have had a menstruation in 16-18. Wherein 18 was fully soaked with blood. Then on march 23 we've had another session of it but mostly rubbing outside and the tip of my penis entering, after a few seconds I pulled it out and ejaculated on the sink. I made her take 2 trust pills about 9 hours later. She had cramps but we cant remember when, didnt know when it was after or before the first or second interaction. She bled on March 29, lasting for 3 ½ days. What do you think is the probability of her getting pregnant?

This was her previous menstruation period:

February 18-22

December 21-23

October 19-20

September 17-19
