Crl size

[July2baby]

So I've been having trouble with baby daddy but so is a friend of mine I'm close to my due date so I'll be DNA testing my baby soon but she's still farrrr from it... You've told me the CRL size of the baby in an early ultrasound is what matters the most but could vary...she slept with these guys 14 days apart from one another is it safe to tell her that the guy closer to her projected conception date off an 9 week ultrasound is the dad...and what would a normal CRL of a baby at 9 weeks be?

Ok thank you:-)

If she got an early ultrasound, and used the estimated due date from the ultrasound (not her period) to compute her estimated conception date, depending on how close the dates of the sex were to the estimated conception date, it might give a clue.  One doesn't just pick the guy who is closer if neither guy is very close.  It's possible that there is a chart somewhere on the Internet that gives you the "normal CRL" of a baby at 9 weeks, but I haven't seen one.
