Spotting.

Hi. I'm 34 and just found out I'm pregnant with my 3rd baby on 4/2. My oldest is 11 and my youngest is 9 months old. I'm super excited about being pregnant again but just wondered if anyone has experienced spotting in the early stages of pregnancy. I've never experience spotting although I did have a miscarriage about 5-6 years ago. With the miscarriage it was just all the sudden I started bleeding bright red blood with clots and everything! It sucked. However, right now what I'm doing is totally different. I noticed when I went to the bathroom, I wiped there was old brown looking blood. So, I decided to wear a panty liner the last 2 days and there has been some really dark brown discharge or blood? Not sure what to call it. It's a very minimal amount and I'm reading that it's normal but since I've never experienced it before I just wanted to get some feedback from you all!
