From the 9 weeks 4 day ultrasound, it sounds like you conceived around May 17. This is not such a commanding lead in favor of the first guy that you never need worry, but it is (even with the margin for error of +/- 3 or 4 days at that point in pregnancy) suggestive that you were already pregnant by the time you had sex with guy B. I think that is the best you're going to get, unless you have a prenatal DNA test. In your shoes, I would be cautiously optimistic that the baby is from the first guy, and would definitely test (with the second guy only if you must) once the baby is born.
My LMP, gestational age and due date dont all add up, but if I put them into a conception calculator they all end uo saying its Guy A.
I got my ultrasound at a free clinic and they told me I was 9 weeks and 4 days on July 9th, but it doesnt add up with my Due date.
How did you get your due date? Did you have an ultrasound? If so, how early in the pregnancy was the ultrasound?
I used conception calculator and they all saidit was guy A from due date. Also Guy A from LMP and since iI dont know my cycle I checked and it can be his all the way up to cycle 35.
http://www.perinatology.com/calculators/Due-Date.htm go to that website might give u some sort of an idea
It's more likely it's guy A's , but since nobody can tell you for sure get a dna test when the baby is born :)
Only way u can be more certain as to when ur conceived is knowing ur ovulation I was im in ur situation but knowing my menstrual cycle and when I ovulated really helped me good luck .....
Not really su how long my cycles last.
If you have a 28-35 day cycle, I'd say guy A is the father...but if you're not sure its best to get a dna test!
How long are your menstrual cycles?
I would say most likely guy A but a paternity test is the only way to be sure
It sounds more like guy A to me as well. However, I think you'll probably need a paternity test to be sure. good luck hon
