Am I ovulating?

I took this test this morning. I wasn’t supposed to ovulate until the 22nd. Can you ovulate 4 days early?? I only have had sex once in my 5 day most fertile window (NOT KNOWING it was my fertile day window.) 🙄😓 so obviously I’m going to BD today and the next few days but I’m so bummed that I may of missed out.

Anyway, do you think this is a strong positive that I’m in fact ovulating? This is the Walmart brand.... so I’m not even sure.
