Kick locations

Victoria • Expecting baby #1 September 2019! ❤️🥰

So I’m now 18 weeks and 4 days. I’ve been feeling some light kicks (or so I think) for the last week. Mostly when I’m sitting down at work or at night lying on the couch. My question is is it really the baby if I’m feeling the kicks in my lower abdomen? Or is it just fluid being moved around? I would have though by now the baby would be up closer to the base of my belly button. I’m asking now because I think he just kicked real hard and it made me jump lol. Completely took me by surprise.
