I don’t understand. Each month I regularly get EWCM around the ‘fertile window’ and each month my period comes bang on time, but I never get a positive OPK. I switched brands this month to Clearblue digital hoping it would make a difference (maybe the other brand was faulty idk) but still negative. 😔

I guess I can try body temping next?? But as a mouth breather due to allergies, I’ve heard temping can be unreliable? Any tips? TIA.
