thick white discharge- chlamydia?

Hi,

I've recently been experiencing very excessive amounts of thick white vaginal discharge (smooth, no lumps). I was treated for chlamydia earlier in the year, and have been back with the same partner since (but not anymore). But when I had it the first time I had cystitis like symptoms- is it possible to have different/no symptoms if i had caught it again or would it be the same? I've also just come off the pill, could that be causing the discharge?

Thanks
