Scared

Hello ladies. I have a question for those who have been pregnant or are pregnant. This is my second pregnancy after my ectopic I had four years ago. I also suffer from pcos but i recently found out im pregnant. BUT im bleeding or spotting pinkish or sometimes brownish blood. I have a docs appointment on Monday for more on it but I’m scared anxious and nervous bc the bleeding is there. Any advice? There are no clots or dark heavy blood or cramping. My back just hurts any advice?
