Faint positives and some negatives

Looking to see if anyone else had this experience... AF was due today. I’ve been taking hpt every morning since Thurs (and to be honest, some during the day too), and I’ve gotten mostly REALLY faint positive tests or negative. Idk what to think. When i had my son, by the day before AF, you couldn’t mistake the positive test - super dark line. I understand even a faint positive means pregnancy, but I really don’t want to get excited if this is a chemical pregnancy or likely to be a miscarriage. Anyone else have this experience?
