It does sound like you conceived around December 19, unless the doctor did not give you that date from an ultrasound.  If it was simply counting from your period, have you had any ultrasounds that confirm you are on track with that date?

When did you have sex with your boyfriend, only November 18 and 19?  That would be way too early to produce the pregnancy.  Or when you say November 18 and 19, you didn't mistake the month, right?

If you had sex on December 16 and 17 with someone else, and no sex with your boyfriend around that time, the December 16 and 17 guy is most likely to be the dad.  It may be that you used condoms but they are only considered to be 80% effective.  They are supposed to be put on almost before the guy becomes erect and not removed until well after the event, and no touching of genitals after.  Sperm could certainly live in your system for three days or more if some escaped the barrier of the condom.

Hi, Janjan,

You do know that pregnancy is dated from the first day of your last period, right?  Doctors count from the first day of your last period, or from the presumed first day of your last period if they have an ultrasound in hand that places the baby at a certain date.  When a woman tells her neighbor, "I'm 11 weeks pregnant!" she is likely also using that counting system, because she gets that count from her doctor.  All the books use it, like "What to Expect When You're Expecting."  So, when you tell people how far along you are, use that same medical way of counting.  Today, September 29, based on having an ultrasound on August 21 that said you were 10w5d, you are 16 weeks 2 days pregnant.  By the last ultrasound's measurements, you conceived around June 21, give or take a week.  But the main point is, you didn't get pregnant in May whether or not you had a period.  You didn't even get pregnant in early June.

Nope I slept with the second guy only from June 6th . I just am a little afraid cause this last time I just saw the nurse she gave me a wheel and it's basically range from the end of February to the middle of march I can have the baby but it's just funny cause that puts me still at conception early June .. Could I have got pregnant at all in May lets just say even if I hadn't had a period?!!

An estimated due date of March 12, if it was gotten from an early ultrasound, gives the following.

Probable date of ovulation:  June 19
Possible dates of conception:  June 15 to 23

This is why I asked if you slept with someone after June 6, because above, you only gave the choice of a guy may 24, and a guy June 6.  

What does "I only slept with the second guy all of June from 06/13" mean?  Is that someone else other than the June 6 guy?

Also, did you have sex later in June with anyone?  I'm not getting very early dates from what you are saying, not even June 6, unless the guy on June 6 had very long-lived sperm.

well i believe i did go in between four to six weeks, and he did do it based off the first day of my lmp but he also did measure the embryo. it really isn't going to help is it until i have that ultra sound ugh this is terrifying :(

It all depends on how accurate the estimate of March 4 - 17 was.  

Do you know why they gave you such a wide range of dates for your estimated due date?  Was your ultrasound quite early?  (An ultrasound in the fourth week, for example, is hard to read, so a medical person reading it would hedge their bet by giving a range.)  

Do you think they gave you that range just based on the first day of your last period, versus on the ultrasound information?  It matters in answering your question, because first-day-of-last-period kind of measurements only work for women who are as regular as clockwork, with the classic 28-day cycle.  For a woman whose cycle is not average length or regular, an estimate based on it will not be helpful.

If you think the doc actually did the get the edd of March 4-17 from what was seen on the ultrasound and not from when your last period started, you could plug the 4th it into a conception calculator and the 17th into a conception calculator, and see where that puts the first guy (if it does).  Both March dates take you into June, from the 7th to the 28th.  So that would be guardedly good news for your wish that the second guy is the dad.

But as I said, you can't know how the doctor got his or her estimate of your due date (giving a range is rather unusual) and if it was simply counting on a calendar rather than measuring the embryo, it is not necessarily a definitive.  You need that next ultrasound.  :)

So are you saying that if my edd shows between march 4th and 17th then if the conception date comes up around the tenth or twelve of June then it's likely the second guy

Well, 7 out of 8 is not 8 out of 8.  There is a one in eight chance of the morning-after pill not working.  Do you have a reliable due date from an ultrasound, or is that what you are waiting for next Wednesday?  If you get one (an EDD, estimated due date) from the doctor or ultrasonographer who sees and measures the embryo, you should be able to plug it into a conception calculator and see which guy has the strongest chance.  You can't really entirely rule out guy #1 until you know how far along your embryo is, and that is better done by ultrasound than simply by knowing when your last period came, especially if the only reason it came is because you took Plan B.

Do you mean regarding the first guy or the second?  The morning-after pill (I guess you are calling it the day-after pill) gives a 7 out of 8 chance of preventing implantation of a fertilized embryo if you take it within 72 hours of the unprotected sex.  It would therefore have no effect on the second sex you are talking about but would have a 7 out of 8 chance for working on the first.

Yeah when i put it in on this app it says conception date was june 12th. When i used baby2see.com it says possible dates are between the 8th and the 16th with your most fertile day being the 12th. So as long as you actually got your period, you should be ok.
