Mini pill

I consistently take my pill daily so not an error on my end. I check my ovulation just because I know with the mini pill there is still a chance you can or could ovulate. I ovulated or had a positive opk 11/5. It then went much lighter like it’s supposed to. Now that I am due for my period 11/19, this Friday, I decided to take another opk. Looks positive to me and I’ve heard people say that’s how they found out they were pregnant before an actual pregnancy test. Any insights would be great. TIA
