Teen pregnancy and realtionships?

well my ex gf is in the hospital right now about to have her first kid... and well there is a possibility that i could be the father... sucks kidn of... considering that it will be 9 months since we broke up on feb 20th, and it was about this time 9 months ago that we last had ... so its kind of scary to think about it really... considering that we spent so much time apart... and that we've had so many relationships between the two of us since we broke up... and... i just dont know if its possible for me and her to get back to gether ever again...
