Could I be the father?

My ex-girlfriend cheated on me frequently, which is why she is my ex now, but apparently she had sex with a guy twice between April 5th and April 11th, with one time for sure being on April 11th. The time on April 11th she and the guy were drunk and he ejaculated inside of her without protection. Her and I had been dating for a year and a half and we hadn't had sex for about a month and a half, but had sex on April 18th. I (because I'm stupid) did penetrate without a condom but I pulled out before I ejaculated and did not ejaculate on her (but I know pre-*** can cause pregnancies). The beginning of her last period was March 30 or 31st, 2009, and her due date is January 5th, 2010. According to the ovulation caluclators she would have been ovulating from April 10th-15th which would coincide with her encounters with the other guy. They told her a few weeks ago that she was 4 weeks pregnant, which would put the conception date at the 2nd, but I believe she misunderstood this for her LMP, which would make sense since she said that she did have a period that started when stated before. So we subtract two weeks from the 2nd and it would put it on the 16th, the Jan. 5th due date came from her last Ultrasound in which she was 7 weeks pregnant. So, to wrap up, since she had sex with someone while she was fertile on April 11th unprotected, and I had sex with her on the 18th (2-3 days after she came off her ovulation), what are the chances that I'm the father (if any)? I've pretty much already come to believe that I'm not the father, but I would really appreciate some professional help. Thank you!

it does sound like she's screwing with you. you sound like a great guy who would take responsibility for your actions. i.e. a child. you wouldn't abandon them if s/he is yours. she seems to know this and is stringing you along just in case you are the dad (or not) and hopes you become instadaddy. i've seen it happen a million times. yes there is still the chance you're the father but IF you are....you DON'T have to be with her. you can be involved with the child (and if there is proof s/he is yours) she has to give you visitation rights. that would be your right. so don't let her trying to "get her cake and eat it to" keep you from living your life. go to the beach. be a teenager and HAVE FUN!!!! let that week just be your escape from her. don't take your cell phone. or if you do keep it turned off. don't talk to her or have any interaction with her. let your mind be free. when you get back her and the baby will still be there. the paternity test will happen and you will finally have your answer. but don't let her tell you how much she wants you back while she's sleeping with other guys. if she really wanted to be with you she wouldn't be sleeping around. that is not love. that is wanting instadaddy.

Its ruining what could be the best time of my life, right after we broke up she decided to become friends with my friends (while in our relationship she barely even talked to them), then while she is sending me texts how I'm the only guy for her and how she wants me back she sleeps with two other guys, then we hook up again, then she goes back to sleeping with other guys, now that I know the story I know how much she has screwed me over. I don't want anything to do with her and I want to move on but I can't, I just had my last day of high school on friday, and I graduate this upcoming thursday, and I can't have any fun or flirt with any girls because I have this huge psychological barrier. I've done the math and worked out the dates a million times in my head and on paper and on the internet, but I still can't shake it. I just wish I knew for certain. My grandparents got me a room at the beach for senior week, which is the week before she will be able to get a DNA test. I wish I could know before then.

then it most likely is the other guys but you're going to have to wait until the paternity test is done to have a 100% accurate answer.

Pretty positive, they coincide with her LMP and Due date given, her ovulation dates put her fertility from in its entire range (low-medium-high) between April 8th-April 15th. She had sex probably between April 6th-April 9th with the other man, and definately on April 11th. From my research women can really only get pregnant from sex five days before ovulation and during ovulation, in which all of these dates would lay. I didn't have sex with her until April 18th. Thats why I don't think it could be me.

She is going to get a prenatal paternity test so we can know who the father is in a few weeks, but this is still driving me crazy... I don't think it is possible for me to be the father because we had sex after her ovulation. I think she was already pregnant when we had sex.

the only way you can know if you are definitely the father or not is to have a paternity test done once the child is born.
