Ok I'm so lost in who the father could be. I am 15 weeks right now. I had intercourse with one guy dec 25. And a different guy jan 3rd. Who is the father?

The one who will match the DNA test you have to do when the child is born. The dates for sex are too close to know which one it was.

If I had to guess based on dates and how far along you are, I would say the one in January, but sperm can live for several days in the womb, so Fr. Chuck is correct in saying the DNA test is the only way to know for sure. The dates are just too close. The reason I would guess the partner in January, is because it makes more sense based on your 15 week gestation, but if that hasn't been accurately identified through an ultrasound (typically done at 18-20 weeks, and still not 100% accurate) then it really is up in the air. Not that it isn't already. Best to be safe and have the DNA test done after birth. You will want to know who the father is for sure in case your baby develops medical problems later where family history is important. It would be far worse to let someone fall in love with "their" baby and then learn 2-3 years down the line that it is not their's at all.

I wouldn't even guess at this. Wait until the chld is born, have DNA testing done.

Anything else is pure guesswork. I've seen Physicians make mistakes in calculating due dates, when a person got pregnant.

Family medical history AND support for the child are important.
