SPOTTING, but period is 11 days away!

So, I have a 35 day cycle! I am sexually active & I am desperately working on baby making! On the 23rd I had brown spotting & I did not have sex that day or the day before. On the 28th, I work up with spotting in my underwear- & had sex that night. On the 29th, I woke up with light pink and brown spotting. Not when I wipe- only in underwear. Creamy white discharge for like 2 weeks straight too.

My fertile window was January 21st-January 27th.

Could this be possible implantation? I have two ovulation calendars. One says I am 3dpo. The other one says I am 5dpo.

So, implantation or period coming early? Period is due February 9th.
