Positive on clearblue but today I got light red stains. Should I be worried?

Positive on clearblue (3 days before actual period) but today (1 day before my period) I got light red stains. Should I be worried? I am having sore boobs, light cramping and a little nausea with burping as a pregnancy symptom. Please help. I had a chemical pregnancy last 2 months and now I'm very anxious 😞 #TTC
