chart analysis?

So
So this is my first time tracking bbt, using opks etc after my mc april1st (it was my first and it took ten months to finally get a positive. We lost it at eleven weeks. Literal heartbreak). 
Can you guys let me know when you think i ovulated? And does the lack of increase in temperature suggest no pregnancy? 
Second period after mc is expected Sunday. 
Thx! And sorry for the glare.
