Ultrasound can be wrong, right?

[BLTombs]

Alright, well, I'm having a little bit of an issue myself. I was with my husband back in November 2012 and i'm sure we concieved on the 15th or the 16th but I hadnt been having any periods for over a year to start with.
I didnt know I was pregnant until february, I didnt have a baby bump until about two weeks ago and now my bump is HUGE.

I didnt get to have an ultrasound until yesterday, which from my calculations should be 17-18 weeks but the doctor insisted i was at 24 weeks. That's not possible. I didnt have sex in september or october but the doctor kept insisting he was right. I dont know what to do and it's stressing me out.

Is it possible that my baby is just huge? According to the ultrasound it's a girl and almost 2 lbs. They only took the measurements and it didnt look accurate at all. .

My expected date is some time in june. The doctor didnt give me a specific day

Just to be 100% about partenity,  you can talk to your doctor about in utero test,  but its way white a long short with your hubby unless you had an encounter with hubby in September you might have forgotten.

Thumbs upbringing your husband. Am amazed that there are still such men in this world whose love is do transcending everything else. You are one lucky girl. And I agree with Brooke the baby is likely to be ex and indeed u/ s doesn't  just look at baby size they consider a host of things like open or closed nostrils,  development of fingers calcification of certain horns lung dvt. Even behavoural traits that can be distinct for a particular cohort.   If you still feel strongly about keeping baby in spite of your hubby 's offer, you can talk to your ex and give baby up for adoption. There are many pple who would be willing to adopt your baby. Hugs

You said "some part of me just can't accept carrying a child that doesnt belong to my husband," was that to explain why you resisted what the doctor said so strongly, or is it because you would have wanted to terminate the pregnancy if you had thought the baby is not your husband's?  There is always the option of allowing your ex to adopt the baby (if it does turn out that your doctor was correct and the baby proves to be his).  I hope you don't have to make those choices, and hope that your new doctor tells you the other one was full of beans.  But I'm glad you're keeping open to the possibilities instead of just denying the possibility.  When not in confusion and anxiety, you can think, and you might see that things are not as impossible as you originally felt.  Your husband doubtless said what he did out of his love for you.  My husband would want to raise a child of mine even if it wasn't his, because he loves me.  You're in a good position.  Please take care, and I wish you good luck.

Well, thank you. I feel very fortunate to have him and thank you again for the help!

See another doctor, get another ultrasound.  Just keep an open mind about what the first doctor said.  Good luck!

ps -- That is a husband worth keeping.

The only time I had sex with my ex was on Sep. 15 because he was visiting from out of state and i asked him the exact days he was off back when he came to visit me.

It just doesnt make sense that I could go so long coming up negative without any symptoms and he didnt even finish inside of me.

My husband said it didnt matter because we would be raising the child and it would still be "our" child, but some part of me just cant accept carrying a child that doesnt belong to my husband.

I feel like i'm really just venting now and it's kind of helping me come to terms with the possibility of my ex being the father.

Thank you for your response, it was very helpful and informative.

Are you sure of the date of the fling with the ex?  If the doctor is right, or close to right (and I hate to say it, he probably is closer to being correct than you are giving him credit for), you would have conceived around September 30 or October 1 or 2.  An ultrasound in the 24th week can be off by a bit, like a week or ten days, if the baby is growing more slowly or quickly than average.  Add to that, sperm can live up to five or six days in your reproductive tract, giving the date some wiggle room.  But a doctor visualizing an actual baby on ultrasound will not mistake a baby conceived in late September or early October for one conceived in mid November.  He doesn't just look at how big your baby is, there are growth milestones; i.e., the development of certain bones and internal organs and all.  If you were writing in and saying you feel like the doctor is off by two weeks, that wouldn't be too surprising so far along in the pregnancy.  But you're insisting that the doctor has to be six or seven weeks wrong.  If the doc was just measuring your tummy with a tape measure, you could go with that, but he was looking at the actual baby with an ultrasound.  I'd begin to prepare for the possibility that Mister Ex is the dad.

I was mistaken. I remembered the other day that I had a fling with an ex on september 15.

However, because of my job, I had a mandatory pregnancy test late the following october and early november, both of which were negative.

I'll definitely go try to get a second opinion, because it just doesnt make any sense no matter how I try to look at it.
