i would defo go to the docs, I had the 'snot' like discharge followed by watery discharge that i ignored after other people telling me its quite normal (which it is) but unfortunatly in my case i had lost my *plug* (cant remember technical word) followed by the amniotic fluid which resulted in me going into labour at 32 weeks and having my baby by c section a week later. You can never be too sure with these things get checked out x
I would report any brown discharge to the doctor just to be safe so they can make sure its not preterm labor. I have had a lot of thick discharge sometimes clear sometimes yellow. Good luck.
kinda mine seem to be very yellow ish or sometimes like snot (tmi)
if ur borwnish blood spots are there then it will be from a old bleed nothink much to worry about unless u start getting fresh blood :)
