Pls help!!

Do I just go into the ER if I notice decreased movements?? It’s after 6 & it’s a weekend so I doubt my doc is still in... last time I went into the er for something completely different & I was waiting at least 2 hours to see someone before I decided to just leave

UPDATE: I waited a little longer to see if he would become more active & he did!! I was so worried but my baby is okay & FYI I’m 32 weeks pregnant which is why I was worried!!
