It's possible, but if you are not planning on getting pregnant, you should use SOME sort of protection.
The "pull out" method is ridiculous. It is not effective and pre-c u m can get you pregnant anyway. Sorry to be harsh but this whole question of the "I used the pull out method, could I be pregnant??" is a HUGE pet peeve of mine. It's not a method AT ALL.. You are having UNPROTECTED sex when this"method" is being used..... Geez...
Keep us posted and maybe in the meantime, you should test over the weekend w/ a FRER. Sometimes they are sensitive enough to detect pregnancy 5 days prior to a missed period. Good luck, and again, sorry to be harsh, but c'mon.. =)
Thanks alot for the honesty. Will build the courage to take a test soon.
