Implantation bleeding? when does it happen?

[TotorosOcarina]

I am now on CD37 of a 28-31 day cycle.

2 negative tests (most recent yesterday afternoon)

On CD34 after BDing I had pink mucas on 2 occasions that day,

I assumed AF was coming as I have had cramps for days and am late, but nothing happened and test yesterday was neg.

If it was implantation bleeding should a test 2 days later be +?

thanks

We BD'd again today and I've had another bit of brown gunk, wth is going on ? :(

Not sure, i didnt get any implantation bleeding at all when i was pregnant.
It could be a good sign for you tho as alot of people do say they have that sign before there BFP!!
Hopfully itl be your time fingers crossed.
