17/18dpo but BFN?

[StrawbRhi]

Hi everyone. Hoping someone can shed some light on this months cycle!

I have PCOS and have been on 50mg clomid for 2 cycles. Seems to have regulated my cycles to roughly 33 days. Doc says progesterone on day 21 is low (2) but have been getting positive opks that coincide with ewcm and ov pain. Took this month off as DH and I were in different countries so figured clomid would be pointless!

Had ewcm and ovulation pain on sept 16th with a slight rise in bbt so think ovulation took place. Saw DH and DTD the next day.

Since 5dpo I have had nausea, vivid dreams, headaches and wind. More recently sore boobs, bloating and fatigue among a host of other symptoms. Took tests with fmu on 14 and 15dpo (weds and Thursday) but both neg.

Since Thursday night though, I've had very light brown, odourless and watery discharge that is so pale it would be hard to see on anything but white toilet paper! Does this count as spotting? Or a period?

I'm not heartbroken if this isn't my month as I never expected it to be but I'd really like to find out what's happening so I can get back on the clomid! Any advice would be gratefully received.
