Your welcome

[leeleebee1]

thank you lauren

[LaurenMH]

So the baby can't be your exs. You were pregnant already when you slept with him.

[LaurenMH]

If you conceived on feb 10th then on feb 25th you'd only be 15days pregnant nothing would of shown on an ultrasound.

[leeleebee1]

are u saying that because you don't know.

[mrsMartinez91]

Be up front with the guys and get a dna test that's the only way to know.

[leeleebee1]

so there no possibility and how so sure?

Ultrasounds are really accurate very early in pregnancy. The first trimester most babies grow at the same rate because its the basic body forming, so no,  there isn't even a chance your ex could be, you were already pregnant.

[leeleebee1]

how can you be so sure? im just asking kinda worried

[LaurenMH]

No chance if you were 6wks at feb 25th. If it was your exs on feb 10th you wouldn't of even known you were pregnant on feb 25th.
