ftm 12 weeks question

I've noticed lately that I've been feeling like a pressure kind of in my belly, sometimes the pressure will like move around a little bit, like now I feel it on my right side and earlier it was kinda on my left side kinda close to my belly button but a little bit to the left of it and a little lower than it. Could the pressure be the feeling of the baby or am I just like imagining things?? I don't really know how to explain the feeling. I don't feel like any butterflies or anything just pressure sometimes.💕💙
