I agree, sounds like its your boyfriends baby.
My due date is August 18th and i conceived November 26th. So it definitely sounds like your boyfriends.
Ultra sounds are usually right on point for measuring and determining how far along the baby is! The only time it would be of is if the baby isn't developing on point in which the doctor would tell you if the baby is not developing on point! As far as determining who is the father in all reality a DNA test is the only for sure way to determin if you had unprotected sex with one or more people!
On a side note: for the fact you had your period after you had sex with the first man most likely he is not the father!
