Sounds like a good plan :-) Good luck!
iv been spotting for 4 days, just not enough to ware a tampon...or a pantie liner, what confussed the hell out of me is my temps are not as low as last month, iv taken a test the ept and that was negative and i tock that today. so what i will do is i may go to the doctors tomorrow if my temps dont go down....
Since you're 16 dpo, it could be your period about to start...or maybe implantation. Implantation is a long process, so even though a possible egg started to implant several days ago, you could still get implantation bleeding at 16 dpo. If you don't get your period within the next few days and your temps stay above your coverline, take a test!
Best of luck to you!
this is my chart i forgot to ut it up...
