FF removing crosshairs at 15DPO?

Thanks for your reply :) while I do take my temp at the same time every day, I don't always get the sane amount of sleep because my son is still not sttn...and he wakes at different times every night. *sigh* I was very surprised to get my +OPK so late (at least compared to the last 2 cycles). This is becoming quite obnoxious lol. Surprisingly AF has not shown yet, although with a temp so low this morning I can't imagine she's far off. I should also mention that I am battling my second cold in 2 weeks, which can also explain some of the wacky temps I suppose. I was hoping that the temp dip at 9 dpo was implantation but then there was that second one and it was all down hill from there. Who knows. Thanks again for your reply and insight.
