I'm 30 weeks pregnant. My LMP was 09/20/10. I had protected sex on dates 10/2/10 and 10/5/10. I had unprotected sex with a different guy on dates 10/8/10 and 10/22/10. On 10/22/10 I am sure he ejaculated inside of me. I am unsure who the father is?

You'll have to wait until the birth and get a DNA test done.
