Possible implantation early pregnancy?!

Okay ladies, my period is in 2 days but I went to the restroom yesterday and when I wiped there was a very light red pink color and I’ve not had anymore blood since. This is not normal for me, I never spot before a period and my periods are usually on time. However I am ttc! So along with this light colored blood is headaches, backache, tiredness, nausea, and my sense of small is really strong. Any chance this is implantation bleeding?! (I took a test and it was negative..🙁)

UPDATE**

I started bleeding the 20th and it stop but this morning when I wiped there was light pink... again... is it still possible I can be pregnant
