Spotting, maybe tmi

Olga • Two boys' mom, fitness addict
So, I had LH surge detected on my ovulation tests oo Sept. 2, we had intercourses sept. 1, 3, 4. I took three pregnancy testes on 10 and 13 dpo all were negative. Yesterday was the 14 dpo and I had just a very little spotting in the afternoon (it was like two pinkish-beige dots on my pad) and had light to medium cramps. I thought it should be my period (which is gonna be today or tomorrow) but from the time I got spotting there is nothing and my cm is white and creamy. So, the question is could it be the late implantation or it is strange beginning of my period?
