Does anyone understand these results???

The Combined Parentage Index is 197,007 (corresponding to a Probability of Paternity of 99.99%, assuming prior probability = 0.5) and
indicates that these genetic data are 197,007 times more likely if Joe is the biological father of Anna than if an
untested, unrelated Caucasian man is the biological father. This genetic analysis excludes at least 99.98% of Caucasian men from
paternity. These results do not supersede any genetic testing directly involving the biological mother of Anna. An extended
analysis was performed in this case and results in a Combined Avuncular Index of 2,248 indicating that the genetic data are 87.64
times more likely if Joe is the biological father of Anna than if he is her uncle.
Conclusion:

Joe is not excluded as the biological father of Anna.

by simple i mean like tell tell signs, physical appearance or birth lines or even cheap home dna testing.

Prenatal (before your child’s birth) DNA testing:
Amniocentesis: This test is performed in the second trimester, anywhere from the 14th-20th weeks of pregnancy. During this procedure, the doctor uses ultrasound to guide a thin needle into your uterus, through your abdomen. The needle draws out a small amount of amniotic fluid, which is tested. Risks include a small chance of harming the baby and miscarriage. Other side effects may include cramping, leaking of amniotic fluid, and vaginal bleeding. A doctor's consent is needed to do this procedure for paternity testing.

Chorionic Villus Sampling (CVS): This test consists of a thin needle or tube which a doctor inserts from the vagina, through the cervix, guided by an ultrasound, to obtain chorionic villi. Chorionic villi are little finger-like pieces of tissue attached to the wall of the uterus. The chorionic villi and the fetus come from the same fertilized egg, and have the same genetic makeup.
How much did it cost? Did you have any side effects and was the baby ok?
Here is the reason I want to do it!

Ok so I got put into a situation that really sucks. Let me give you guys a little history of me and this girl. We dated for 3 years, she cheated on me and we haven't been dating for the past 2 years. I am 20 and she is 21. I live in California and she lives Michigan. So i go back to Michigan back in Oct and ran into her. We ended up having s*x 3 times.....1 time without a condom( I know I'm stupid for doing that). We haven't talked since the other day and she tells me that she is pregnant and she doesn't know who the dad is. Well finally the truth come out and she told me she has and had a boyfriend at the time. She's been with him for a year. I just want to know if its mine Cause if its mine i want to be there throughout the experience. If its not mine i don't want to waste my time and money when its not my responsibility.
