What just happened!! 😬

OK guys I need help! I am 13 days DPO I have attached my BBT chart with a huge temp drop this morning, but just went to the bathroom and this is what I found! only when I wipe! Eight days DPO I’ve had a sore breast, nauseous, lots of going to the bathroom, abdominal cramping and back pain. HPT’s this morning was negative. Opinions please is this AF for implantation?
