Whos the father of my baby?
Iam currently 14 weeks and 2 days pregnant ( gesteration) I slept with a guy who I really liked on the 1 st to the 9th of December, we went are seprate ways and I stupidly got drunk and slept with a friend on the 12 th of December, my last period was the 26 th of November and lasted 3 to 4 days, I normally have a 25 day cycle, I cannot believe I'm in this situation as this is not something I do, I don't want to be judged, If the dating scan is correct and iam actully 14 weeks and 2 days pregnant then there's no doubt the baby is the first mans, but how acurate are they? Thanks for your help,

How pregnancy is counted by doctors begins on the first day of the last period you had before getting pregnant. For example, a woman has a period that begins January 1, then subsequently gets pregnant during January. The doctor would date her pregnancy as beginning January 1, the first day of her last period, despite the conception obviously not happening on the first day of her period.
A woman with a "typical" 28-day cycle would (supposedly) ovulate around day 14 of that cycle, or January 14. Since the egg is only available for fertilization for one day, conception would happen within 24 hours of that day. So Conception Date is two weeks after First Day of Last Period.
However, women don't all ovulate neatly at the halfway point between their cycles. Often they ovulate early, sometimes late. Doctors don't know when ovulation happens, since it's a hidden event. So they simply backtrack to the first day of the last period (a big, obvious signal), and count pregnancy as lasting 280 days (when in fact, from conception, a full-term pregnancy is 266 days long).
I know that the irony is that this means that a woman whom a doctor or nurse would later call "1 week pregnant" has not even gotten pregnant yet at all, but all medical counting (doctors, nurses, ultrasound techs, growth charts, medical books) is calibrated this way, because of the visibility of periods versus the unseen nature of ovulation. Just think to yourself if your doctor says "Five weeks pregnant," think ("five weeks pregnant, three weeks from conception").
When going in for a scan, a person highly concerned with dating has to be sure her ultrasound tech knows this is the specific question she has. Using language like "how far along do you think I am?" will quite possibly get an answer based on the medical way of dating pregnancy, because that is the world of the ultrasonographer.
I used the first day of your last period (lmp) when I said the pregnancy seems to date from around the end of the first guy and possibly within range of the other. Counting back from the ultrasound on February 22nd takes you to November 29, which really doesn't make a sense as a conception date given that your first date of your last period was November 26th. And it does make sense as a first day of lmp - based date, since by 12 weeks, the measurement can vary a bit (all babies grow at different rates). If you want to get fancy, subtract 14 days from the 12w2 days figure to try to decide when conception was. Unfortunately, that gives you January 12th. If you want to try shortening the 14 day time frame to about 12 1/2 days to account for a 25-day cycle, it comes out to January 10. But unfortunately, again, you simply can't tell from a 12-week ultrasound that specifically.
DNA test is the way to go. Sorry again, but there is no way to tell when everything points to the same few days when both candidates were still possible.

As posted, a DNA/paternity test is really the only way to know. There is no guarantee it's either or no matter how you look at it. Using a calculator with your cycle length, and your LMP your estimated fertility time is from Dec 3-13th which can make it either or.
Gestational age is dated from LMP, which is why when a female is 4 weeks pregnant, baby measures at 2 weeks.

I had my scan at 12 weeks and was 12 weeks 2 days, does this go from around the time of conception? And I had the scan on the 22 nd of feb I do want to keep the baby no matter what x

Sorry, but your possible ovulation date falls right at the end of the first guy's time but could have lagged those two or three days, into the time with the next guy. You can't count on a scan at 14 weeks to tell you specifically when you conceived, since babies grow at different rates, and this is even more so if the choices are only three days apart. Did you have a scan at 7 weeks or 8 weeks (counted from the first day of your last period)? It might be a bit more trustworthy for dating. But even so, the time window between the 9th and the 12th is so tight that it might not have helped any further. After the earliest ultrasounds, they can't pinpoint things to more than a window of a week or even two. If you absolutely cannot have the second guy be the dad, you have some thinking to do about abortion or adoption, I'm afraid. If you're keeping the baby no matter what, it really sounds like only a DNA test after the baby is born will give you your answer.
