PLEASE HELP ME.!!

Monica
Hello Everyone, I'm 24 weeks & 6 days and my baby usually moves not a lot but it moves and today is the 2nd day that I have felt only a few movements, should I be worried.? This is my first baby and anxiously waiting for my baby girl in September. My thing is that I read way too much and it's really stressing me out. I had an Appointment on Wednesday and everything was fine heartbeat is 150 and the OBGYN said that she's healthy... What should I do.??!!
