Possible spotting

I’m afraid I’m misscarrying. This is my third pregnancy, first one was a miscarriage second was a healthy pregnancy. My pregnancy symptoms have been stronger than ever the past two days, but this morning I wiped and got some dull brown discharge. I just went again and got a bit more. I’m at 7w1d and don’t have my first drs appointment for 2 more weeks. I’m trying not to be optimistic but hard when I feel like such a pile of crap. I’m so tired and nauseous. Please give me some words of encouragement!
