Fetal movements at 27 weeks..

Hi girls! So my baby girl has been very active for the last 3 weeks and has began to get into a routine when I know when she kicks roughly.. however the last 3 days she’s been kicking me so hard all day none stop and yesterday and today not so much only maybe 5/6 kicks all day.. is this normal? I’ve been to the hospital and been hooked up to a monitor and also had an ultrasound and they said baby is absolutely fine and no concerns at all but is fetal movement normal to be quieter some days? I was so worried!
