Baby’s pattern

Can a baby’s pattern change the further you get? My baby girl was super active from 17 weeks all the way up until maybe a few weeks ago. I’m 27w1d today and I feel her move and kick daily BUT her pattern seems to have changed. Idk if this is a concern I’m a ftm.. she likes to switch positions a lot, but it seems as if she sleeps a lot now as well.. I feel her in the mornings and at night and throughout the day while I’m at work but she’s just not as active as she use to be which sucks because that was my hope that everything was fine now I’m worried something is going wrong.. is this normal? Or do they develop a more consistent pattern the bigger they get?
