normal cycles?

Ciara
Is it normal to have 32 to 35 days in your cycle? I'm normally 32 but occasionally it goes little past (probably stress related). I've never actually used OPKs to track ovulation, just used what glow predicts and by my CM. Still not sure about some of this but if all that is right my luteal phase is 19 days. Is this normal, or could my ovulation prediction be off? AF is due May 30th. Lots of symptoms but could easily be dismissed as well I feel like. I tested on May 28th and still got a BFN. Not sure if I should keep testing or just wait till June 1st when I go to my doctor. Just feel like I'm over thinking everything and setting myself up for disappointment.
