you guys were right. i'm a week late but yesterday i woke up to find i had started my period.
You're not pregnant, and are looking way too much into this. Abnormal stool is a sign of digestive problems, not pregnancy. What colour is it?
I also noticed that my stool has been colored differently the last three days. I'm not eating anything abnormal...
You would get reliable results from a pregnancy test two weeks after the unprotected sex.
