How To Determine The Paternity Of The Fetus?

default
Posted on Thu, 24 Dec 2015
Question: I am having a hard time dealing with a positive pregnancy test I took a week ago. I got my IUD taken out May 21st and consistently slept with the same person until the 1st of July. I believe I had periods on XXXXXXX 23rd, and july 25th. I started sleeping with someone new the first week of August and on the 19th of August I took a clear blue pregnancy test that read 2-3 weeks pregnant. My doctor gave me an HCG test the following day and my levels were at 3555 and she said I was 5 weeks pregnant but, that doesn't match up with my last period and I'm confused about which man might be the father. Which one is more likely? The one from july or the one from August. I'm stressing out and they won't give me an ultrasound until September 24th. Help!!!!

Detailed Answer:
Hello dear,
Thanks for trusting us about your health care.
I have gone through your history and understand your concerns.
Paternity is only confirmed by through DNA paternity test after delivery of a child.
I can give the most likely father but before giving my opinion I would like to ask a few questions from you.
What is your expected period date in August?
25 th July is 1st day of your menses?
Your cycle is 28 days or 30 days?
First week of August in which date from 1 at August or after that?
Hope to hear from you soon.
Good luck.

I can't wait until after the birth of the child. I do not want to continue the pregnancy if it turns out to be a certain one of them. The other I would continue the pregnancy. My expected period date in August is around the 24th. 25th of July was the first day of my menses but, I'm not 100% positive on that though because I didn't mindfully keep track so my expected date in August is also an estimation. I believe my cycle is 28 days but, I had the mirena IUD put in April 1st of 2010 and didn't have a period until a month after I got it taken out in may of 2015 so I can't be sure. I started having intimate relations with the second man August 2nd 2015.
My breasts started feeling tender and sore on the 14th of August, I have not had any nausea or morning sickness and only slight cramping on August 22nd and 23rd but, I was also working non-stop on those days with very little sleep. My family has a history of twins, August second guy has a family history of twins and July guy does not.

Just trying to give you as much info as possible

Brief Answer:
Most likely August guy.

Detailed Answer:
Hello dear,
Thanks for the description.
If you had proper period in 25 th July than pregnancy is most likely occurs after 25th July.
With your history ovulation in your case occur around 10th August, so the August guy is most likely the possibility( because your fertile days are 4-5 days before and 24 hrs.after your ovulation) .
HCG level can be high due to twin pregnancy.
Hope found useful.
Good luck.
