AF late...ovulation test positive for the last 4 days

I was supposed to start a week and a half ago....tested theee times so far and each was a bfn. I'm trying to hold out until I'm 2 weeks late to test now. I have been doing ovulation tests since I have them at the house. I read they can show a positive for pregnancy also...my ovlation tests have been positive for the last 4 days. I also got a positive two days back at the begining of November before I was late(think I really ovulated then) but I still keep getting bfn on pregnancy tests. I started spotting today so I'm not sure what is going on. Should I call the doctor or give it more time?

Here is a picture....the middle is an ovulation test and the other two are pregnancy tests.
