Determine pregnancy: The first thing would be to confirm your pregnancy with urine or blood test before launching into the maze if who done it, since the situation has legal implications. If you are pregnant, and like to keep the baby, more definitive answer would be a DNA paternity testing.

Conception optimum: A woman ovulates 14 days before the comes on her next menstrual cycle. In a 28 day cycle this would be day 14, in a 24 days cycle day 10, and in a 32 day cycle day 18. Problem is, a woman may gauge when she ovulates from the length of her cycles in the past, but won't know the length of the cycle, she is in. Male sperm after intercourse survives for up to 5 days.
