New to OPKs- multiple positive days? Normal?

Should I be getting such strong positives 2-3 days in a row now? It doesn’t seem like the lines are changing at all. For clearblue it says the smile will remain on there for 48 hours. My period is due in 5 days. Anyone had similar experiences? Again I’m new to all of this, but I wouldn’t think I would be ovulating this close to AF? Top is from yesterday, bottom was taken today without using the digital. Just used it based on eyeballing the lines.
