Hi can I join in?
I too suffer from pre-AF spotting intermittently. I had never had it in the 6+ months after I had come off the pill to TTC, I'd had normal regular cycles.
Then one month, I got some brown CM a few days before AF was due. I of course got my hopes up thinking it was implantation, as it had never happened before. It continued and developed into full AF. I should have learned my lesson not to assume IB...
That happened a few more times, very similar brown CM a few days before AF. Then it stopped, and I went back to having normal cycles.
This month, on CD23 of a 27-28 day cycle, I got pink tinged CM, some spots of fresh blood when I wiped. Never had this before..never been fresh blood. naturally, I assumed implantation and got my hopes up again. That was Friday. Saturday & Sunday, a tiny bit more spotting, but most of the day nothing. Just one or two occasions of pink CM and fresh blood.
Then today, Monday, what seems to be the onset of a light period. Just blood when I wipe, but not enough to reach my panty liner. I'm CD26. This is totally out of the ordinary for me - usual AF comes on with a bang, full flow, cramps, diarrhoea the works.
I am totally, thoroughly, utterly pissed off. I got my hopes up this month, I googled images of 'implantation bleeding' (yuck, why?) and what I had looked exactly like those images. But now it seems it wasn't at all.
I do have suspected endometriosis (haven't had the tests to confirm yet, but the GP suspects it, and I'm certain of it - I poo blood clots during, and only during, my period. It must be endo) - so I do wonder whether the endo is causing the spotting?
No idea, but good to share experiences with people who are going through the same thing. Mama sounds like our cycles are pretty much in sync. I too hate those few days of hoping... and at least when the full AF comes you know where you stand and make a fresh start.
