Pregnancy

Help!! I stopped taking my BC pill 6 days ago and still haven’t gotten my period. On day one of me expecting my period to come I started to get really bad cramps and my boobs felt incredibly sore but nothing. I’ve taken a pregnancy test every day since then and have gotten negative results every time. I had some super light spotting about 2 days ago and then nothing. I usually skip my periods with the pill but I decided to give my body a break and it’s the first time I didn’t get withdrawal bleeding but still getting negative tests. Has this ever happened to anyone else?? Any idea on what my body is doing???
