Spotting and less movement @28 weeks

Okay soo I’m 28 weeks today. I went to the bathroom once today and noticed some spotting? I’ve had some cramps but nothing major.

I haven’t really felt a lot of movement since this morning. And what I felt has been way lower and definitely not as stronger as my baby’s usual kicks. Called the doctor about spotting and they said if it gets worse come in. But I’m just wondering if I should go in now since I’ve noticed less movement. Any advice ?
