Can someone please help?

I just need some insight into what may be going on this month. I haven't yet received a positive opk this month. Last month my cycle was super regular and i got a positive opk about CD 14 or 15. This month my temps are everywhere and Glow keeps pushing my fertile window farther because I am entering a negative opk. What do my temps look like? Is it possible I ovulated early and possibly conceived? I have no symptoms except headaches almost every day. Usually I have crazy sore boobs and a bunch of other symptoms after ovulation but not this month. Someone help!

also, I began taking Maca root this cycle which I think may have actually messed it up. I've stopped taking it. Just super confused!
