almost 8 weeks and I started spotting. should I go to the er?

I'm 7w6d and I've started spotting. It looks like creamy vaginal discharge. When I wiped a few hours ago it was very light pink. Now it's more of a salmon color, with tiny solid-ish clumps that dropped in the toilet. It's not bright red and I'm not having any cramping. Should I go to the er? I'm worried it's just going to keep increasing over the night.  
Also I've been fighting a sinus and ear infection this week, so I'm taking an antibiotic and Tylenol (OBGYN said it was ok). My first appointment isn't until Monday.
