This might be a silly question but how do you know how many days past ovulation you are? Do you just start counting the day after your last ovulation day (green dot on calendar).

If so I am 13 DPO and I was supposed to start AF today but I didn't. I took a test and it was negative. I don't really feel any pregnancy symptoms or period symptoms but I usually feel AF coming a good week in advance.

Does everyone start feeling symptoms by now?! We TTC on November 6.
