Paternity issues :( who is most likely the father ?

Question

Okay well to start I usually have a 30 day cycle. My LMP was December 7 or 8th 2015. My periods usually last 4 days. I had sex with guy#1 unprotected on dec.14th. I also had sex with guy#2 the next day & the rest of december. I found out I was pregnant on January 19th 2016. My first ultrasound on Feb.16 measured the baby at 9weeks and 6days with the due date of September 12-14. Can anyone help me figure out who's most likely the dad, I plan to get a dna test but I just would like another opinion. Or if any ladies have been in a similar situation, what were your results? Thanks :)

It sounds like the doctor based the conception date on your period, but that the ultrasound placed it a week or more later.  I'd trust the ultrasound and assume you got pregnant by guy #2.  Guy #1 is a little too early no matter what.  Get a DNA test after the baby is born, but through the pregnancy it sounds like you can assume the second guy is the dad.

No . It's been the same due date since my first ultrasound. He told me conception was Dec.21-23 because I couldn't remember the exact first day of my period between Dec.7 or 8th. Then he gave me a ultrasound minutes later and that's what gave me 9weeks & 6days from Feb 16th.

From the weeks count, if your ultrasound was February 16, it sounds like you got pregnant around December 30, plus or minus a few days due to the ultrasound being in your ninth week and not earlier.  The only odd thing is that they told you a September 12-14 due date, which pushes the estimated conception date earlier, to December 21-23.  It's kind of unusual for a doctor to give a weeks count and an estimated due date that don't match.  Was your due date changed later?
