Pregnancy risk given these factors

From what i understand precum can in some cases contain sperm that is in the urethra

This is the chain of events ill try to include only relavent details and not be too descriptive

these events took place 2 days ago.Earlier in the day the sex occured i had mustrubated which does increase the chance of sperm being contained in precome

directly after i did shower. I am 90% sure i did urinate before the sex also but i can not be completely positive

During the actual sex i believe most of it was anal, my Girlfriend does however believe i did insert into her vagina but she doesnt believe it was very long. it was her first time so she isnt completely positive about how long i was in her vagina or if thats where i was when i pulled out. The space was cramped so i couldnt actively see either. She is pretty positive that it was in the anus the majority or the time and pretty positive that i was only in her vaginal area for a moment but like i said she is inexperianced and isnt 100% certain

Now as far as her cycle is concerned her period usually takes place on the 7th of the month. the last one however was early (or late idk how youd put it and it ended the weekend of the 26th, she doesnt know the exact date it started but it was ending on the saturday following the 26th last month.

Given all that info is she likely to have been ovulating or is there a chance she will be in the time sperm lives which is about 5 days as i understand?

I mentioned the morning after pill but she doesnt want to take it if there is a chance there was an egg because to her shed be killing the baby which i understand. I told her the other way it works is by preventing the release of an egg, which one of these is more likely give then info i gave you about her cycle?

Any help is appreciated.
