I had sex on Februay 13th and we used a condom but the condom had been stored outside in his car with temp. below zero. He says he didn't ejaculate but I have been in health class long enough to know that their is pre-ejaculation. I last has my period on February 3rd and I was due for my period a week ago. I was wondering how likely it is that I'm pregnant. I told the guy that I was a week late and he laughed at me and said I worry to much and now he won't talk to me. I am not on birth control and never have been. Please help, could I be pregnant.
