So confused by BBT

Chelsie

I'm so confused by BBT. As you can see I missed a couple days. But I've been remembering now. And taking it at the same time each day. I thought I had ovulated on the 10th because of the drop in temp and rise the next day. And I had one wipe of pink discharge on the 15. Then today I wake up and a huge drop in temp. And I'm cramping a bit today. So am I ovulating today. Or does it look like I'm not ovulating at all? I'm so confused. Should I go talk to my midwife about what's going on?
