Hi Everyone

I have recently come off the pill and commenced TTC #1. Today is cycle day 30, normally I have 28 day cycles.
I have done a pregnancy test yesterday and it was negative, my nipples were very tender about a week ago (not as much now though) + cramps + some nausea.
I did a HPT yesterday and it was negative. Am wondering now where's AF? And could I have just missed implantation as my 'symptoms' aren't so strong now?
