Positive Test but idk 😣

Pa

I had a miscarriage in April at 10 weeks.. got a BFP this weekend. My predicted period start date was last Monday. I didn’t think I could be pregnant so when my period didn’t come I just assumed it was still wonky from the miscarriage and didn’t test till Saturday evening. Yesterday I had light brown discharge.. And I feel... angry? Frustrated? Is this spotting just a start to another miscarriage 😞 I guess I’m gonna call the doctor today 🤷🏻‍♀️
