When to test after "possible" implantation bleed?

Ho Hummm....

Can't remember this one for the life of me, so thought I would ask...

How long should I wait after a POSSIBLE implantation bleed before testing?? Where would a bleed put me in my cycle do you think??????? and how long after after DTD does implantation occur???

To cut a long story short, and I am breastfeeding a 7 month old (who is really NOT into his solids yet..but thats another story!:lol:), and haven't really got AF back yet, and not using any contraception....:shakehead:

I had a UTI a couple of weeks back (almost 3 weeks ago) and as part of that they did a blood test for pregnancy just to rule it out, which was negative. (So have been on Ab's to clear up UTI).
I had a very small light pinkish bleed about a week and a half ago.....not sure what this was, but it did occur to me that it could be implantation, because it wasn't really anything like AF (no cramps or anything either). It was just a bit of pink streaking on the toilet paper, mixed in with CM (sorry for TMI!:rolleyes:)..and I have not a clue where I am cycle wise at all....
