Hey ladies! So I am new to this whole temping/OPKs. 
I just ended my period today, I normally run a 32 ish day cycle.. Since I've been working out I am little thrown off. Anyways, in all reality I am
generally on time within a few days. My question is: when do you think I should start using my OPK? Also, any tips and tricks yall have will be greatly appreciated! Hopefully November will be our month! Baby dust to yall! ?
