Lots of movement one day and not to strong the next


Hey guys! I’m 21 weeks tomorrow and just wondering if it’s considered normal that some days I’ll feel my baby sooooo strong and constant and then the next I’ll feel her but they’re a lot softer movements? I’m assuming its just her position? Cause I can feel her but it’s almost like she’s kicking the back of my uterus or near my cervix maybe lol. It’s hard to explain. I feel her about as much as normal but they’re just not as strong. Just making sure that’s normal 😁😁
