is this implantation

so I have too several pregnancy test even blood test all came back negative. with my first child I didn't find out I was pregnant until I was 14wks. I had two periods with her the a missed PERIOD. today after BM(baby making) lol I went to the bathroom wiped and had a heavy amount of eggwhite discharge sorry TMI with a small small spec of pink like blood. can this be implantation? I have had nausea. headaches. back aches. cramping. I am due for AF tomorrow or Friday.But once again with my daughter I was on my cycle until I was 14wks. I have had nightmares and dreams that I usually don't get at all. tingly boobs just not sure what to think with the negative test results. idk if I tested to early or not?
