Thanks for your query.
6 days after ovulation definitely coincides with the time of implantation
, so implantation bleeding is a distinct possibility.
However the odour is not specific for implantation.
Also, occasional spotting is also common, and hence you would not know for sure if it was an implantation bleed, unless you miss your period.
As you ARE trying to conceive, remain sexually active, and take a pregnancy
test if you miss your period.
All the best.
