Had my BFP on Tuesday that evening I started spotting pink then brown then dark red

On Wednesday tested and lines were darker I kept on spotting pink brown and dark red on the evening I would say it was more than spotting but very light still then stopped and so did the cramps( light cramps)

Today I’m cramping again very light and dark red spotting

I’m not having a heavy flow and not passing clots

I thought with a chemical the flow would be heavy like a period 🤷🏻‍♀️ not tested today trying to wait until next week

Anyone had a light flow with a chemical? I don’t know what to think I’m just so scared 😭
