tickling feeling?

Okay so I have suffered from gastrointestinal issues my whole life and just the past day or two I have felt a very strange, slight tickling sensation in my belly region. It's like a flutter and sometimes makes me feel kind of sick because it's a new feeling for me. I'm only 13 weeks and I know it's technically too early to feel the baby kick. I was the biggest cynic a few weeks ago laughing with my OB about women feeling their babies early on when really it's probably just gas... jokes on me! Maybe you CAN feel the baby early?? 🙃
