Paternity: A blood paternity test is the most reliable test to identify the father of a born child. Check: http://www.Nature.Com/scitable/topicpage/paternity-testing-blood-types-and-dna-374.

Ex more likely: Since last full normal period was on nov 14, the day after your 2 relations with boyfriend and since your period is always regular, chances of pregnancy from this relation are virtually non existent, unless LMP was v light. The dec 2nd relation is more likely to have fallen near ovulation and is likely the one responsible. Discuss this with your OB doc who is in much better position to advise you.
