Zero, zilch, nada! ?

So usually my first sign of ovulation (or what I've always labeled it as) is sore bbs. Like clockwork. Well this cycle I've got nothing and my period is due in 3 days. By now I usually am crampy, moody, achy, etc. I know every cycle is diff. And often with no rhyme or reason but anyone else experience this and get bfp? Or on the other (and maybe more realistic) spectrum did you get this lack of symptoms and still a bfn?  Thanks for any feedback! ?
