Who Is the Father? Please Help!
Unfortunately, TeenHealthFX cannot diagnose or treat over the internet. Based on the information you provided, it is very unlikely that guy number one or guy number two are the father. Since you mention having a period and knowing your due date, you and your doctor are able to determine when conception occurred based on your last period. We strongly recommend discussing this with your doctor to make sure that the dates are accurate and will give you a better idea of timing and who the father would be based on the dates you had sex.
If you need help finding a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist.
