Okay, so me and my girlfriend had sex on monday the 25th of Feb. We got caught up in the moment and didn't use a condom. I did however use the withdrawal method without any problems in timing or whatever. Yes yes I know not using a condom was a bad choice, I don't need the lecture, Ive heard it 100 times. Her period started basically the begining of Feb, so her ovulation period was roughly the middle of Feb. Since our intercourse was significantly after her ovulation period (yes I know its not always perfectly in the middle) and Im certain my urethra was clear of sperm from the previous ejaculation, what are the chances that she got pregnant, and what do you suggest we do? She said she expects her period to start up again around the beginning of March, so I figured all we can do at the moment is wait it out and see what happens, and if she doesnt get her period by the 6th or 7th, we'd get a pregnancy test. Does this sound viable? Any other suggestions? Since it happened monday, and it is currently thursday, should we consider the morning after pill in the next few days? Again, thanks for the help.

Questions:
-What are chances of being pregnant?
-Suggestions?
-Morning after pill within the next few days help (if so, what brand do you suggest)?
