Confused by Ovulation Tests

K

I’ve been using this app to track my period, and during my fertile phase I had 2-3 days of positive ovulation tests (the smiley face ones). It’s been 10+ days since then and I’m due to start my period on Dec 9th. I was curious what would happen if I did another ovulation test right now just for fun since I have so many, and I happened to get a positive test again! I’m confused how this is possible…am I pregnant or can you have more than one surge?
