Feeling defeated after AF shows up early.

Ly
I'm feeling very defeated, this is my third month ttc. I started my monthly today not only did I start I started about 2 days early. I really thought this month would be our month. Idk what I'm doing wrong I'm taking prenatal's, tracking my bbt, and using opks. I've started taking evening primrose oil I stop taking it as soon as I get a positive opk. Idk what to do at this point.
