I am on the pill and I've been taking them correctly at the same time. I notice that navel hurts on and off. Does that mean I am pregnant?

No. Pain in the navel is not an early symptom of pregnancy. If you are taking your pills correctly, pregnancy is very unlikely. Your occasional pain in your navel may be musculoskeletal or gastrointestinal in origin. If this is a significant problem for you, see your PCP for evaliation. Hope this helps.
