How many days after possible implantation bleed could I get a BFP?

[dottyaboutstripes]

I had some brown tinged creamy cm on cd17. I generally ov on cd11 but was paying no attention whatsoever to my cycle as my dd has been in hospital having a big op, so I have no idea if or when I might have ovulated (this cm was DEF not ov related)

I was wondering how many days after that would be a good day to start testing? Of course I could wait until AF is due or just rears her ugly head, but that's not how it works, eh

When I got implantation bleeding it started on a Sunday afternoon finished Monday evening and then got a very faint BFP on the Wednesday morning. Hope that helps. It was only spotting. Good luck

Could be ovulation bleeding or implant bleeding. Stress of operations on the body can delay ovulation. Based on your normal cycle, when is af due?
