Advice! Insight please!

I had my Mirena removed on the 7th of Nov. i started ovulation testing the next day. 2 days after the removal I got a positive opk, I called the doc to verify that it could happen, they said yes. A couple days later i started bleeding. I took that as removal bleeding.... i wanted the two week wait and have taken several pregnancy tests that are negative. So I took an ovulation test today just for the heck of it and it’s positive! So I’m lost and confused! What do you guys think of this?
