Recently I received news that I may have gotten a girl pregnant a few months back. I slept with a girl 1 time with a condom and don't finish in the condom in the girl. Upon further discussion it could possibly be 3 other guys. I have read numerous stories about guys being stuck with child support even when the child is not theirs. Mid 20s. I do not want a child at this time in my life. This occurred in California. A few questions. -How do I protect myself from this eventuality if it is not mine? Lawyers? Doctors? -How accurate are the ultrasound predictions at 2.5 months? - Any other things I am not aware of I may need to know from others who have been in this situation?
