Weird question about implantation.

So I know sometimes we can see or notice implantation bleeding, well itd be around implantation time for me and yesterday I noticed when I wiped I noticed a lot of cm so oddly enough I decided to smell it, I know weird but just wanted to make sure it didn't have a smell. Well I noticed it smelt of blood. I thought it was strange sense I didnt see any blood. So I guess my question is, could that have been implantation.
