I'm 18 weeks and starting to get nervous. I think I'm feeling movements periodically, kind of feels like popcorn popping. However, I don't feel it all of the time, and I normally feel it in the upper portion of my abdomen, not in the lower portion where I know the baby is. Help!!!

not unusual to feel movement there at all, however, think you posted in the wrong board. LOL. The babies head is downwards, and the feet are towards the rib cage, which is normal.
