Is it too early?

I know every woman on here asks this question... so here is mine. We have been ttc for 13 months now. My lmp started 6/15 we "baby danced" 25, 26, 27, 28, 29, 30 I think I ovulated on the 28th. I used a saliva fertility tester and had ewcm. My cycles are anywhere from 28-33 days. On last wed, the 2nd cd 17, I had pink dishcarge twice. (implantation? )Yesterday was CD22 and I had a qualitive blood pregnancy test done which cam e out neg... was it too early to show up? The qualitive only gives you a yes or no, not the actual count of hcg in your blood. Or do you think this cycle is shot and I should stop my racing mind
