Pregnancy Uncertainty: Possible Father?

Question
Ive been with the same guy for 5 years we have an 18 month old together and i cheated about a month ago i just found out im pregnant but the guy i cheated with came on my back and never was inside me while my boyfriend and i have had unprotected sex for the past 5 months iam so scared that it is the other guys do you think its possible? please help im panicking! thanks kiley

Answer
there is a chance it could be the other guys even though he didnt cum inside you. If he was any where close to you the semen could have run in or even pre-cum could have.  But I think it is safe to say it is your "main" guys baby just bc youve been with him more often and on a regular basis.
