29 weeks and fetal movements

So I'm a first time mom and I'm having a girl well the past couple days I have been more emotional than usual and my baby girl usually moves a lot rally in the morning and when I go to bed and steady throughout the day, today I started feeling like my muscles were very sore and she hasn't moved like normal she has done this before and I always get paranoid but she ends up moving again, is she just sleeping or should I go into labor and delivery just to be safe?
