Hey..Sounds like your pregnant...But get a test either from the doctor or a womens health facility/clinic. You will need to get a dna test done to find out who the baby's father is, you will need to do this especially if you need/want child support from the father. You will need to talk to a doctor about the dna test, im not sure if they can do it before the birth, most wait until the baby is delivered, they may be able to check through an amniosyntesis.(however, most women don't feel comfortable doing that.) I would keep both of them in your lives for the time being, until you can be sure who the father is. And maybe even after the father is revealed, if both still want to be part of the circle, you may find it beneficial, after all, they say it takes a village to raise a baby. Good luck...Oh yeah, and if you learn nothing else from this experience...Use protection, no matter where you are in your cycle.
