What was your experience?

Hi everyone, this ttc thing is hard because it seems like most everything else you can turn to the internet for some solid answers to any questions, but not with this! I am 2 days late for my period and have had mild cramping the last 6 or so days. I was fully expecting to see AF yesterday but never happened, then today I have even less cramps than yday. Today I have felt slightly nauseous and sick to my stomach. Some CM but not a lot, white in color. Tenderness in breasts and a bit more tired than usual. Took a PT and it was negative. What does anyone think? Would love to hear from any and all.
