Implantation Bleeding?

Hello Glow Ladies!
My husband and I are currently in our second month of TTC! I'm about 5dpo and am not expecting AF until February 8th.
I have noticed that I've been slightly more tired than usual and have had tender breasts. 
My cycle is usually spot on, so today kind of threw me for a loop. I just went to the bathroom and noticed a little more than a tinge of pink in my discharge. I also checked my cervix position - its high and soft. I'm not sure where it should be if you're pregnant..
Does anyone have any opinions on what this could mean? I would appreciate any thoughts you may have! (:
