help....ovulation.

Is this positive for ovulation? I took two and they were identical. I also took a clearblue advanced and it was a blank circle. So I'm very confused. I am also still breastfeeding my five mi the old could this have anything to do with it?  It seems like my cycles are very off. Last two periods I the I had two in a row with pain so I figured it was ovulation and now no pain. Last two cycles were about 33-35 days. I know it takes a while to get your fertility back after being pregnant. I would appreciate any advise....
