Yes the second person. Especially if you know your last period and when you had sex
You had 2 periods that were regular....yes it's the second one...ultrasounds don't lie it measures the fetus and can show exactly how many weeks you are.
Not necessarily. ..the body doesn't always function according to medical textbook standards even though it would sooo be so awesome if it did....guy #1 could be daddy2be. I think that you should explain to your doctor and pose the question but if not, definitely get a DNA Test. Best wishes.
Sperm doesn't live 2 months (or two periods time) in your body. It could only be the second person.
Yes I would think the 2nd guy!
it sounds like there's no chance of the first guy being the dad
If the baby was measuring bigger yes, my last pregnancy I had a normal period for 2 months however I lost my baby. So it is possible to have a period and be preg and but unlikely it's the first guys unless u are measuring further a long
You dont need a dna it's the second by the looks ov it you missed 3 periods unless your baby is measuring that far back the second guy 100%
