chance of pregnancy??

Sorry, this post may be a little bit long but I'm just trying to clarify some things. This cycle, I have been more aroused than I ever have been in my entire life (sorry, TMI). I had unprotected sex on cycle day 8 and cycle day 13 (I'm guessing I ovulated right on or right after this day because of the way my CM was) but using the pull out method. I know it's possible to get pregnant from pre-cum, or pre-ejaculation fluid if we want to be technical here, and I feel like I was possibly extra fertile this month since I was so incredibly aroused. I'm now on cycle day 18 and I've noticed an excess amount of creamy and thick CM - excess for me anyway, and I've heard that this could be an early sign of pregnancy. It's a normal color and there's not weird smell, so I'm not worried about a yeast infection or BV. Is it possible that me being more aroused than normal could mean I was somehow more fertile this month? And how high are my chances of pregnancy? I obviously know that I'll have to take a test to find out for sure, but I'd like to hear some insight from women who have been in similar situations.
