What is this?

Little back story, this is my third pregnancy. With my last pregnancy I developed two large PE’s 10 days postpartum making this pregnancy high risk. To top it off I was diagnosed with PCOS after her pregnancy so it took 4 years to conceive this baby. I am currently 16 weeks and have had a little brown spotting for the past couple days but when I went to the bathroom a few minutes ago I found this. Can someone reassure me it’s normal, or should I go see a doctor? Freaking out a little. I never had spotting with either of my other pregnancies. I know I little spotting is normal but this just seems like something more?
