Do you think I will ovulate?

My period ended on sept 25 and then on oct 3 I started getting brown spotting. Today it is red/brown. These are my ovulation tests all the way up until yesterday. I had a negative pregnancy test. And I'm not regular but it's always hard to get my period to start or to stop. It doesn't come often like this. But what do you think is up? Do you think I will even ovulate? Should I keep testing for ovulation or? Help?? Thanks!
