How likely am i to be pregnant if he came inside? i had my period dec 25th-jan1st. i had sex on the 10th and today the 11th.

Hard to tell...: If a woman is fertile and has sex during her fertile days (usually around days 11-16 of her cycle), there is a chance of getting pregnant. We count cycle days starting from the first day of bleeding of the last menstrual period, december 25 in this case. All she has to do is to wait for the next period. If it is a week late, she can check a urine pregnancy test.
