Bleeding between 5-6 weeks

Hi everyone. I’m currently pregnant with my first. I thought I was 6w5d but I have PCOS and don’t ovulate regularly and based on my ovulation date my dr thinks I’m less far along and closer to 5w3d. Anyway, I had some very light brown spotting earlier this week. My husband and I had been intimate so I figured that was the cause. Today it has turned to red and blood like. The amount is still small (about a teaspoon or less) but naturally I am concerned. I’ve seen a lot of similar posts here and people saying it’s normal and not cause for worry yet but wanted to post this to the group myself to get thoughts. Any insight or help is appreciated!
