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 strong as my baby’s usual kicks. And it’s only been once or twice since this morning. I 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 ?
