Hi Glitterball
I've read that the NHS are very anti clomid for women who are already ovulating, although like you I think it's worth a try. It sounds like you have a good specialist though to have put you forward for the investigative lap - I really hope it gives you some answers.
My cycles like yours are around 24 days, I think it's really interesting the month you stopped your supplements you had no spotting - a 9 day lp is short but still possible for implantation and seems preferable to starting spotting at 6dpo. I hope pre the lap the spotting stays away for you.

I've been googling today, in fact I think this is becoming my LP obsession, googling brown spotting/discharge. I'm cool all cycle and then when it hits I just desparately want answers.
Anyway, today I noticed several sites describe 'spotting' as a small amount found only on wiping.
Is this what everyone gets?
Also, do you ever check internally on days with no external spotting to see if there's anything lurking internally?
It's made me wonder if mine is spotting or actually regarded as bleeding. Mine is there everyday, if not externally then there's plenty internally when I try check my cervix (sorry if TMI). When it's a discharge, it's enough to mark underwear/a liner. It also changes in colour, thickness, wateriness/dryness over the week.
