Basal temp tracking

Goodmorning ladies, I am 31 with pcos. We accidentally got pregnant in November and miscarried a couple days before Christmas. We were shocked but oh so excited and felt so full but then pure devastation. I started tracking basal body this month as my doctor recommended this if wanted to precede prevention. We decided not to prevent but to see what happened, obviously both not expecting a thing. I’m 7-8 DPO and last night my CM was tinged with blood and was almost like egg white with the blood in it. This morning a little pink when I wiped. Period due in 8-9 days. This is my chart, what do y’all think.
