I don't know what im looking at please help

Nicole

I'm new to bbt charting and I don't know what I'm looking at all. last month I was 5 days late, when AF finally came it was purple and clumpy. Ive never has a clumpy bleed before. I'm not expecting af to come on time because last month was so strange. will somebody please help me read this mess?

did I ovulate on day 4?

when should I expect my period?
