Limited fetal movement- 27 weeks (anterior placenta)

Hey all! I’m 27 weeks pregnant and I’ve had very inconsistent and sometimes limited fetal movement. Some days the baby feels active and then I’ll go a few days will very little movement. I have an anterior placenta which makes it “harder” to feel movement but this is also my first pregnancy so I don’t know what to expect. I’m nervous that the 28 week fetal monitoring will start soon seeing that it would be rare that I have 10 moments in 2 hours. Any advice or experience?
