Me and my girlfriend have had a few scares... actually i've posted about all of them here on the tfp because I <3 you guys so much and it eases my mind. I'm glad you've chilled out a little on the whole thing - I'm a hateful person so I can probably guess what you edited out, and the thought ran through my mind the first time a scare happened, but then I just thought about how happy I was with this girl, and how much she meant to me, and I really didn't give a damn about my big plans in life or our families, I just wanted to be with her and have a happy life - whether it meant a baby or not. I don't really know what I'm trying to get through here; I guess it's the fact that we all have been through or will go through a scare like this at least one time, irregardless of how careful we are. You're not alone here, and I just hope everything turns out okay for you two.
P.S. - After our scare my girlfriend and I cut out really everything sexual. And I've found that I just love her so much more now. She's now not only my girlfriend, but my best friend of all. *shrug* I used to think sex was everything - until I started doing it.
