Ok I looked at your chart and I need to k ow a few things. First, when did you DTD? Which days? Am or pm? Also, did you have CM? When? It's possible you ovulated on CD 14, it's that second pos OPK that is throwing everything off. Maybe late on the night of cd14, hence the +? I think your chart looks great. Still too early to tell, but IF you O'ed on cd14, you would absolutely get a positive tomorrow, because you implanted at 5dpo.. I hope this makes sense.
If you O'ed on cd 16, I would expect a pos (if you're pregnant) by wed at the earliest. Just my thoughts!! Take them with a grain of salt!
