ANYONE WANT TO GIVE ME ADVICE!?!

Nikki • Mother of A beautiful tomboy .. Two Angel Daughters. & TTCIng our rainbow baby 🙌🏻🌈
So basically I'm going to make this short and sweet! I was suppose to start my period today, as of my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> which is usually dead on or a day off. 
I checked my cm internally yesterday morning with some tissue paper, and saw blood tinged cm. So for sure I assumed my period was about to start. I woke up this morning and was shocked to see nothing . I've been checking my cm all day internally and NOTHING! 
Just light EWCM. No blood. And usually when I see blood, my period is usually to follow.
Any advice?
Implantation?
We've been trying for 6months now.
Cervix is low and breast are sore. That's my only symptom.
