Orange Blood/discharge

Katie • Hi! I am 28 and TTC my first. I am so excited! I am an attorney, wife and step-mom. My step-daughter is 10.
I am on CD 37. I thought I started my period today. But it's just this orangish discharge. Anyone have thoughts on this? Miscarriage? I didn't get a BFP this cycle or anything. But it may have been too early to get one. Also-I had a UTI late in my cycle around CD 24
