I am stuck in a very complicated situation. I just went to the doctor last Thursday. I found out through an ultrasound that I am atleast seventeen or eighteen weeks along where my last appointment they estimated about thirteen weeks along right now. My current boyfriend and I got together fifteen weeks ago and started having sex thirteen to fourteen weeks ago. Before that I was seeing a coworker, who I would love to be the father of my baby. The coworker came in me and wanted to get me pregnant, where my boyfriend always pulled out. My boyfriend has no idea he may not be the father, but has become super annoying. I don't know how to break it off with him. I would love to eventually get back with my coworker and raise a family with him, just don't know how to even pursue that. Any suggestions? Who do you think the dad is? I got with my current boyfriend May 24th and began sleeping with the the first part of June. I'm thinking with how much the baby has developed by the ultrasound that it is my coworkers baby.HELP!! :)
