Need help with BBT, Ovulation while breastfeeding

Hi all! I'm not sure if you can help but I am still breastfeeding my 11 month old and AF hasn't come back to town yet. As you can imagine, tracking ovulation is tough. I started to get back to taking my bbt every morning since May 27th. We are hoping to get a baseline so we can try for a second baby soon!

Here is my chart so far. Have I ovulated yet? It's been a couple of years and I feel like I lost most knowledge on it lol. Of course, my LO had a rough night the 5th so I got less than 3 hrs of sleep on the 6th so no temp taken. Also, the coverline should be ignored since it's from my previous cycle in October 2017 😋

(Yes, 580 something days without AF, gotta say I don't miss her!)

I've taken three test strips the past few days. The first is from Saturday. I assume since they got lighter, maybe I ovulated sometime last week? I only bought them late last week so that's why I didn't take it sooner. Any insight would be appreciated!
