Is it the baby?

M🌺
I have This feeling really low in my stomach (uterus area) that feels like someone is inside there poking me! It always happens around the same time everyday. When I eat something sweet, lay on my stomach and when it's time for bed. I know it isn't gas because it only last for a few seconds and it's in the same exact spot every day. Could it be the baby? It happens a lot when I press down on the area also. I go to the OB tomorrow morning and I'm 13 weeks.
