Without : Without knowing when your last period was, it's difficult to tell who may have gotten you pregnant. Timing things from the last period is the most accurate way of dating a pregnancy. Ultrasounds and measurements can give an approximation, but they may be off by a few weeks which doesn't help you in your situation. You should talk with your ob/gyne doctor. Since they have all of your information, they may be able to give you a better idea of whose baby he/she is. Good luck!

Legal issue now: Without firm dates/cycle history you don't make this determination. You can get paternity testing as early as 10 wks with a NIPS, non invasive prenatal screening using fetal cells isolated from mothers blood. These results are compared to the possible donor dads to come up with paternity. Discuss this with your OB.
