Thanks you very much for the valuable information. I keep trying to recollect even if I had sex with her during the month of July to September but just can’t pin it down but I know it was in 2017. I’m going to give her few days to be with this child and suggest dna test next week. This is very stressful for me as I have no desire to raise a child nor pay for child support but I put myself in this situation. Thanks again
There is no point at looking at whether she had only a 20% chance that month of getting pregnant, she got pregnant. That was her month, meaning whether the odds were slim or good, this was the month she beat them. If you had sex in the right time window, you could be the dad, though your condom use helps you to an 80-85% chance you are not the dad.
The figure for condom effectiveness has to do with whether there was body contact prior to putting the condom on (the recommendation is to put it on when still soft, I cannot imagine people really doing that, but it is to prevent pre-ejaculate that might contain sperm from reaching the vaginal secretions), and also includes other factors such as the semi-mythical "the condom had a leak" or "the condom broke," and also the more realistic "the condom slipped" or got stuck on withdrawal. All a guy can do who doesn't want children for total certainty is to get a vasectomy. Condoms are a lot better than nothing, they are just not 100%.
The fact that she got pregnant shows that this was her month, whether or not the odds are considered low to get there in the first place. At that point, you calculate the odds of the condom use helping you.
I assume you mean the baby was born 5/10/2018?
If you can'r put a date to when you had sex, then you will need to go the DNA-test route. Be as nice as possible to her, don't argue about it. But tell her you do need to test, and see if it brings up any information from her about when you were together. if she continues to refuse testing but to say you might be the dad, see an attorney.
Hi, Jamie,
Your age won't make any difference. Men can have kids into their 90s.
And protection is a good thing, but I'm sure you know condoms are considered only 80% effective. You and the other guy could have both worn condoms and she could still have turned up pregnant. Or, he could have not worn protection and you could still turn out to be the dad because there was a gap in protection and some contact happened during the gap. In short, whether or not he wore a condom is not going to exonerate you, so you may as well assume she is telling the truth, for the purposes of not insulting her. You will need her cooperation to get to a paternity test.
You might be able to knock down her story on the dates, though, if you have any records. Can you associate the times you had sex with any other (non-sexual) event that happened at the same time? Can you locate any record, such as a credit receipt for dinner, or a record of something else that you did that you can associate with the event (like, you had to take your car to the shop and she gave you a ride home?) Assuming you must have had sex in August simply because she is claiming you might be the dad, is kind of nuts. (For one thing, it couldn't have been in early or mid August if the baby was born last week. You would have had to have sex from August 22nd forward, maybe even later, to fit the timeline.) It frankly sounds from the fact that she is not willing to take a DNA test like she is pretty sure you aren't the dad, but has just not admitted that she has ruled you out. Maybe you are giving her loads of attention and it makes her feel good? Maybe the other guy is horrible? In your shoes, I'd distance myself from the woman a bit, not call her anxiously and talk it over a lot. She might figure out a way to bring herself to tell you that she was mistaken.
Anyway, as I said in your other post, you can't do this with a drugstore DNA test. They are too prone to error and fraud. You need to talk to the family law court where you and she live, and ask the judge's clerk if there is a list of labs approved by the courts for legal determination of paternity. Then you, she, and the baby (and ideally the other guy also), go there with ID and do the test, handing the swabs to a neutral third party, a lab tech. Do not do a swab from a drugstore test and hand it to the woman to mail.
If she won't agree to a test and it is worrying you, call a lawyer or go to a legal-aid cliinic. Find out what your rights are in a case like this to insist legally on a test. It is possible to get hit later in life for costs of a child, so take it seriously, but don't freak out. To me, her behavior suggests that she sort of does not think you are the dad any more. If that is what is going on, do your very best to give her an opening to tell you this without feeling like she looks like a fool.
