My girlfriend said her period was a week late and she got it on December 26, 07. On Jan. 10 we had oral and i ejaculated on her chest and some on the neck. I wiped the semen off and a little while later she took a shower. She is now 12 days late but, she was supposed to get her period on January 26. but now its Feb. 5. If she was supposed to be late again would that mean her period is only 3 days late? We just had finals and she goes to softball practice everyday. Plus tryouts have been held the past two days and shes been eating differently this month. Could she be pregnant? We are both very scared any advice will help
