I have never been pregnant, or maybe I could answer this myself...I am on the pill and don't expect to be pregnant any time soon. However, I have a weird feeling in my stomach. It is exactly the way your stomach feels when you are on a roller coaster (dropping sensation). It has been happening every 30 minutes or so for the past two days and it won't go away. I have 2 days left until I am supposed to start my period, or else I would just take a test. Could I be pregnant? I have never had such a wierd feeling. I am baffelled!
