I started feeling something new this morning. Butterflies and maybe kicks In my lower right tummy? It first felt like a heavier thud, tapping. It's a weird and somewhat startling feeling. It didn't feel gas at all. But I could be wrong. I remember my doctor saying the feeling of movement usually starts between weeks 15-20. Has anyone had what they think to be kicks this early?
