How long can a sperm survive in woman body?
We were fighting a little bit so started having sex from 12th November, on 6th December she did a pregnancy test and informed me she is pregnant.
On 10th December she did an ultrasound that she sent me and it says due date 5th August, baby age 6w0d.
On 13th January another ultrasound that says due date 5th August, baby age 10w 6d.
Later ultrasounds I don't have, but the first 2 convinced me I'm the father.
Week ago I found out she was having sex with another guy before I came, so 1st November could be last date she had sex with him, and she convinced him he is the father, and he is also convinced saying everything lines up with him being the father, he said he talked to the doctors and they told him it adds up to time he was having sex with her.
I am totally confused, how can he be sure he is the father when first 2 ultrasounds give me conception date exactly 12th November, can later ultrasounds change due date or conception date, she is having a boy, could it be bigger because boys are relatively bigger (I was 4.5 kg) so that ultrasounds he saw give him results he wants to see.
Don't ask me about her period because this girl obviously lies a lot, as far as I know it was at end of October, but that can't be verified.
What I do know is that she got some symptoms while I was still in Bali, on 21st November, last time we had sex it was a little bit painful for her, she had some vaginal discharge, her breast were extremely sensitive, she was also feeling extremely tired all of a sudden.
First time she mentioned she feels nausia was 4th December.
If it means anything for the results, she is a healthy Indonesian girl, 160 cm, 50 kg.
I know I have to do dna, but can you maybe give me an opinion who is more likely the father, can I send you the ultrasounds to look at them
cannot be decided conclusively on basis of history
Hello sir, thanks for trusting health care magic.
I totally understand the anxiety involved and the legal and moral implications of this fiasco in your life.
But I don't want to give a false assurance to you because despite of ultrasound co - inciting with your intimacy with her it can still be his baby (though his chances are really less).
The point in his favor is the fact that -
1) sperms stay in vagina and cervical mucus for 72 hours many a times and this can cause pregnancy after 3 days of sexual activity
2) ultrasound in first 3 months of pregnancy can be vague in calculation of weeks by 5-7 days.
Both these facts if taken together can result in a pregnancy from an intimacy between the other guy and your girl.
So paternity test is the only conclusive evidence proof that will decide it.
In case you have any other question, please feel free to ask.
observer errors are common in ultrasound
Hi, I did look at the scans. They are only pictures and nothing much can be concluded upon by them.
I can understand the confusion in your mind but ultrasound is a very subjective thing which depends on simple calculations and a minor difference of a fraction of a millimeter can cause a difference in gestation of about 2-3 days.
You are right that early ultrasound examination is most precise but it still has an error of 5-7 days and in later month errors increase to the tune of 2-3 weeks.
So precision is more in early months definitely but still margin of error increases.
Your ultrasound picture is coinciting with the gestation but still it is just a picture and not a real time evaluation and this picture will be freezed, measured and calculated by the software in ultrasound machine and thus will generate automated result showing the gestation.
But if picture is freezed erroneously due to various patient and doctor factors then software is not going to correct it and will rather calculate accordingly to the freezes measurements.
I know this information is disheartening but i want that you should be fully informed about all the aspects so that in case there occurs any legal argument then you can put forward these facts.
Nausea is also a very subjective feeling and can start as early as 7-9 days post conception or may take 3-4 weeks to start so that cannot be accepted as a solid evidence.
All in all a paternity test is a must but in my opinion the child is yours.
All above discussion is just an enumeration of remote possibilities to tell you the problems involved.
Most probably your baby
Yes dear, that's what I told you that chances of it being your child are more definitely; but all above discussion was to give you an idea that in case the other guy also consults some specialist he can put forward these points to emphasize his right on the baby.
Whole thing was to make you aware of all the possibilities.
not related to each other
No dear, gestational age calculation is independent of the weight of the baby or parents.
So it is not the cause.
Moreover ultrasound done in later months are of no significance as far as gestational age calculation is concerned so you need not to even consider them when you have two ultrasound reports corresponding with the fact that the baby belongs to you.
paternity test needed
In case she manipulates her period date and hides the first two ultrasound reports then without paternity test noone can prove that it is your baby.
So better opt for latter option to claim the baby.
