Is a butterfly feeling in your stomach an early sign of pregnancy?

No, that's anxiety. Early signs are missed period, frequent urination, and tender breasts.

I had a feeling like this when i was pregnant with my 2nd. but at the time it was still to early for a pregnancy test to read positive. they kept showing up neg. until about 3.5 to 4 weeks later. meaning i fealt this practicly as soon as i was preg. I don't know if it is normal though.
