Difficult to say: More likely the dec partner, but timing should have been up to a week before ovulation...Which "might" still result in pregnancy. Jan date should give a october edc. May get better estimation of conception with later pregnancy ultrasound, particularly if due date shifts. Or will need paternity testing.
