HELP! ADVICE! Can this POSSIBLY be implantation bleeding and not my period???

Let me say in advance. sorry for TMI!

In a nut shell. My DH and I have been diagnosed fertility problems and in a few months we are planning on undergoing IVF. However, here is what has been occuring and I am confused!

I use the Clear Blue East Fertility Monitor and NEVER ovulated (reached peak) this month? (the past three months of using it I had peaked) Is it true if you are pregnant you wouldn't ovulate? I believe so!

I've been having tender nipples for two weeks now!

My period is ALWAYS one to two weeks late..usually a 40-44 day cycle.

WELL...I am technically due for AF tomorrow. (remember I am always a week to two weeks late) Ever since Friday I am getting a little pink and brown when I wipe myself (implantation?) but nothing is staining on my underpants (sorry TMI). I took three pregnancy tests this weekend and they are all BFN's. Of course after seeing this my hopes are very low but does anyone know if I was just possibly experiencing implantation beeding now would a pregnancy test show up yet it I was in fact pregnant? It just seems so werid to me. I am NEVER on-time..NEVER..yet alone two days early. Any its not lilke a period. It's odd! I am so confused but a bit excited for the possibilites of a dream come true post having to go through IVF. What do you all think? Am I dreaming for no reason?

Thanks,
Keri

If you were PG and still testing for ovulation, you would get all positive OPK's. HTH
