Ovulation confusion

Stephanie • Mother to a sweet baby girl born 14 October 2015 💗👑💗
So last cycle I used ClearBlue digital advanced opk and had 5 highly fertile days (cycle days 8-12) and peak days were 13&14. This cycle I bought a bunch of non-digital opk's on amazon and I'm confused. I thought I got a positive opk on cycle day 14, but I took a test this am (cycle day 17) and it looked positive too. Last cycle I had intense ovulation cramps on day 13 and so far nothing with this cycle. Also, I can't make any sense out of my bbt chart. I'm feeling frustrated. 
Middle pic is from cycle day 13 on 10/5...thought that was positive until I got this (below): cycle day 17 (10-8) . I've attached my bbt chart too if any of you kind lovely ladies could help me interpret this I would be so grateful!! TIA :)
