Implantation?

I have been ttc #2 for about 5 months now. Starting Saturday night I had alot of very creamy discharge with a very very small dots of blood mixed in, but not everytime I wiped, this continued through to Monday and then Tuesday it stopped and started again a little bit Wenesday and now nothing it just stopped. Could this be implantation!? I took a pregnancy test and it's negative, maybe still too early?
