Bbt charting help?

This is such a wonky chart. Crazy crazy lines everywhere so I'm having difficulties understanding it. Considering it has 2 drops past the cover line after ovulation, and now it's going back up. Anyone experience this? And still get BFP? With the temps decreasing I was sure AF was going to show her ugly face, but now the temp is elevated. What do you guys think? And yes temps are taken at the exact same time, every day. Haha
