Quick question

So this is my chart yesterday I started to have severe cramping on and off and the cramps got worse throughout the day. Then I got some light spotting only showed up when I wiped. Today after I had a bowel movement the severe cramps went away now I’m having twinges and light cramps I’m still spotting not even enough to soak a pantyliner. At 2 am my SO started craving ice cream he even said I don’t know why but I’m craving Ice cream. Could this be a good sign?? I tested today it was negative but I tested at 9pm. Do you think I still have a chance or it’s just AF creeping slowly with a 2 day spotting
