Hi so i just found out i was pregnant...but heres the problem my last cycle was nov.28 and i missed for the month of december my question is when was i  ovulated if i had intercourse on dec.9 protected and dec.14 unprotected.....when should my due date be?

Did u get a due date? @anniebrooke u are so good I agree

The doctor said i ovulated either on the 12th or 13th. And i dont have anyway of getting in touch with the first guy we are completely out of contact.

Conception calculator says for the due date of September 4:

Probable date of ovulation:  December 12, 2012
Possible dates of conception:  December 8 to December 16, 2012

If one guy was on the 8th or 9th but pulled out, and the other guy was on the 14th and ejaculated inside you, then we are back to the first statement I made in this thread, "generally speaking, if you had protected sex with one person and unprotected sex with another, the father will be the person with whom you had unprotected sex."  But that's just speaking generally.

Unfortunately for the sake of being sure, the guy you don't want to be the father is the first guy of the two.  Although you only ovulate once and the egg only is viable for 24 to 36 hours, sperm can live for up to 5 days in a woman's system, so his sperm could have been in you from the 8th at the time you ovulated.  If the doc thinks you conceived on the 12th or 13th, and you didn't have sex with the guy you want to be the father until the 14th, it still leaves the question open, even if the guy on the 8th or 9th pulled out.  You could have ovulated a day or two later than the doctor says, and then the baby would be your boyfriend's, or your guy on the 8th/9th might have had some sperm in his urethra from an earlier ejaculation and have gotten some of it in from pre-ejaculatory fluid.

I am sorry, but this is one of those where I strongly recommend a DNA test.  Is there a way to test quietly with the guy who is not your boyfriend, to rule him out?  (Of course, don't tell him that is why, or he'll have his buddy go to the lab for him.)   It really wouldn't be fair to your boyfriend to have him be raising a child thinking it is his, when it is not.

Yesterday was the big day the doctor said im 10weeks and the baby is due on sep.4th.......i got to see the baby move around and hear a heartbeat. He said i shouldve ovulated around the 12th or 13th so it should be my bf (the second date) what do yu think?

"that you could the count from the actual first day of your last period would be reliable" is supposed to be "that the count from the actual first day of your last period would be reliable."

Try to relax as much as possible, you will get your ultrasound pretty soon now!  Remember, they'll give you an estimated due date and a number of weeks pregnant using a count that begins on the first day of your last period, not a count from conception.  Be sure to ask if your estimated due date is based on the measurements of the embryo, rather than just being based on you saying when your last period began.  (As I said before, if your boyfriend is in the room and you don't want him to know there is a choice of possible fathers, just say your period has been a little irregular and you weren't sure that you could the count from the actual first day of your last period would be reliable.)  If your doctor says "you're x weeks pregnant," ask him "From conception?" since doctors often use a figure that begins on the first day of your last period.  You want to be clear as crystal on what the doc is saying.
