Hi My Name Is Kat I Am 20 Years Old,

Hi my name is kat i am 20 years old, my husband and i are trying to concieve. The first day of my last period was the 23 of december 2016. The number of days between each period is 24 days. We had intercourse on the 27th and 28th of december 2016 (no longer bleeding on the 27th) i would really appreciate an answer to how likely i am to be pregnant in this situation. Thank you so much.
