implantation bleeding?

Posted in another group but didn't get much feedback. Possible tmi (no pics) : it's two weeks before my expected period and 7 days after possible conception. I had faint spotting yesterday and faint spotting today, with scant clear tissue I saw in the toilet. What would you think... Implantation bleeding or no? Obviously I'll have to wait two weeks to really find out but based on this info and your experience, what would you think? Also, I had implantation bleeding with my second child in case that matters (if pregnant this would be my third).
