You must calm yourself and be solid towards her. Tell her that if it is proven to be yours, you will stand by her. Who knows, this may be your future. I'm not sure that "pulling out" is the way to go though., if you want to be in total control. Maybe rethink that form of birth control. Over the years i've heard that hasn't always worked. Good luck. You have 9 months to prepare for any outcome, so relax.
Ted, it's unlikely that if she is pregnant, that you're the father.
If you had sex 7 days before her period was due, that would be unlikely to cause pregnancy, especially considering you "pulled out".
I don't know how to suggest you proceed, but you're not alone out there - there are LOTS of men who ask the same question you're asking on this forum.
Hi i believe 10 days is the correct window period for a test to be accurate but since you pulled out i highly doubt she pregnant with your child. I agree with you about the uneasy feeling. At this point all you can do is get a dna test done. You might want to talk to your family doctor on how to go about that test.
