Hi my last period was march 5th 2013, it last until march 11th, I am now 33 weeks pregnant with a due date of December 10th 2013. When did I most likely conceieve? And is it possible that I could have confused implantation bleeding with my last period even after the doctor gave me a due date? Could I have gotten pregnant in February?

You know your due date... it was 9 months before that with a window of actual conception of two weeks before that date to two weeks after it... meaning it happened sometime in that 4 week period. Medical science can not be more specific than that in this day and age.

Is there a paternity issue at stake here?

Smoothy is right

To add to that, implantation bleeding IF there is any, would be spotting... very very minimal and observing any blood during implantation is very rare to begin with. It's highly unlikely you confused implantation spotting with a period. Your doctor's dating is the best information to go on.

You would have ovulated APPROXIMATELY 2 weeks after your period started but that's only an average. You could literally ovulate at any time after a period.

Well no, not actually. There's and ex girlfriend claiming to pregnant as well. She's due December 14th literally 4 days after me. My boyfriend does admit to having intercourse with her, but before we got back together. We got back together February 23rd. If he didn't cheat she would be due before me correct?

Or maybe he cheated.

That's what I was thinking. He claims he was drunk so he doesn't exactly remember anyway

So I for sure got pregnant sometime after my period in march correct? Cause it lasted for 6 days and I ovulated on the 19th

You conceived after the 11th of March. You can't say that you ovulated on the 19th. That is a good guess, but it could have been before or after. Regardless your due often reflects the date of your last period not the conception date, and even then it is scaled to the size of the fetus. It assumes that all fetuses grow at the same rate to the same size. So there is a bunch of wiggle room.

If he was Boinking her right before you got together then it could be his depending. It is odd that you got pregnant immediately, but ca sera.

The only way you're going to know if that kid is his is a DNA test afterwards. Farting around with conception dates and due dates is going to cause nothing but grief.

I find it weird that iim due December 10th and she's due December 14th. Is that even possible?

Why wouldn't that be possible?

Why wouldn't that be possible? I don't know. That's why I'm asking cause I don't understand. This is my first pregnancy. I just want to know if it is possible

Of course it's possible that he cheated on you. As a matter of fact, if that is his baby he DID cheat on you.

yes you are right but I don't know either she's lying or he's lying. But he is getting a dna test for sure! I find it weird that iim due December 10th and she's due December 14th. Is that even possible?

When you've got personalities like you describe it is completely possible. The one thing I know is that nature is a funny and fickle fiend.

What are the possible scenarios here:
1). Your boyfriend is telling the truth, but there is the possibility that he's the father of both kids.
2). Your BF is telling the truth but isn't the father. The EX is trying to do this to drive a wedge in your relationship.
3). Your BF is telling the truth as accurate as he can remember and the paternity might be his because he cheated.
4). Your BF is lying because he cheated on you and knows it and is trying to pull the wool over your eyes.

Until you know for sure assume that he's being truthful. If you start assuming that he's being anything up truthful is when doubt creeps in. Then you'll never trust him. That will be a cancer upon the relationship until it finally dies. What happens when the family splits up?

Honestly this is a funny situation. How long were you going with him before you two because exclusive? It sounds REALLY fast.

I love how you broke it down to me. But it's been two years of us being together. We live together now and everything. I just thought it was akward that we were that close in our due dates. But he doesn't even remember when it happened. And he claims she didn't know we were together, which she for sure did! He didn't expect her to get pregnant so that's his karma. But he doesn't want to be with her if it is his child he will be a father that's it.

And pay child support too, I hope.
