Hi, I have been having unprotected sex. I am not due for my period for another four days but I am experiencing the following symptoms: fatigue, nausea, craving, heightened sense of smell. Like yesterday I craved a bacon cheeseburger with fries I added barbecue sauce and ketchup to the burger and fries. Then the following day when I eat breakfast I crave barbecue sauce with my eggs and of course I added the barbecue sauce to my eggs and ate it and found very delicious. Weird yes I know. So I'm wondering if there is a possibility that I am pregnant.
