Very light pink spotting

I just went to the bathroom before bed and noticed some pink on the toilet paper. I’m 5weeks 2 days today and don’t have my first ultrasound until 10 weeks. This is my first time being pregnant so I’m kind of freaking out. The nurse at my doctors office told me when I originally called to schedule the ultrasound that if I had bright red bleeding or was filling a pad every couple of hours to call in but that’s not what is happening here. Do I call the on call doctor, go to the ER, or wait and see what tomorrow brings? I haven’t had any cramping or anything except when I sneeze I get a little cramp on both sides for a second.
