Questioncan paternity be determined before giving birth?
Answer Possibly, although to be honest I do not know how likely it is.
This is rather new stuff to do it before the baby is born exspecially in certain areas of the country. (small towns etc) It is done by a needle inserted into your stomach then into the ambilical cord. It is a sort of risky thing so if you could wait it would be better.
You will have to talk to your Dr. about it. Good luck to you.
