28 weekers baby going through a sleep phase

Felicia
Are any other Momma's that are 28 weeks along feeling less movement? My girl was very active the beginning of the week and the last two days she's been sleeping I suppose! I still get little nudges here and there! Just wondering if maybe baby is going through a sleeping phase or a growth spurt! Just worries me! 
Update! 
This afternoon my baby girl was pretty active! I guess I just worried a bit to much! I'm so happy to see I wasn't the only experiencing less movement!
