12dpo red streaks in thick creamy discharge

[Bturny24]

Help!!! I'm 12dpotoday!! Took a test w fmu BFN!!! Checked my cm this morning and it was thick, sticky and yellow!! I checked it after lunch and had red streaks in it!! It was still thick creamy and sticky!! AF isn't due until Thursday or Friday!! I still have mild pinching cramps that I've had since O date and my boobs are still real sore especially underneath and on the sides! Does this sound like IB????? I didn't have that w my son I only spotted brown at 7wks preg which my dr told me it was the placenta attaching and growing!!!!
