According to FF, I am 9 DPO. I think it's a big fat liar

My temps haven't gotten very high this month, so I don't believe I Od. If I did, my post O temps are only about .2 degrees higher than my coverline. Usually they are much higher than that. I keep bouncing back and forth. If I am 9 dpo and this were a regular cycle, AF should be showing tomorrow or at latest the next day. Of course by now my back and breasts would be sore. Neither hurts right now. I'm trying to convince myself I either haven't O'd yet or am having an anovulatory cycle. I hate uncertainty. I've been taking B6 to lengthen my LP. So maybe it'll be longer and that's why my back and breasts aren't sore.
Have any one else seen a difference in temps with B6? I'm wondering if that could have caused my lower temps.
