Spotting before period TTC?

I have been spotting pink/brown and it seems watery also for a few days now. I keep cramping like im gonna start but i have never had this spotting before. I usually get a clumpy thick brown discharge 2 days before but i have not seen that yet just pink/ brown when i wipe or drips on a liner. im confused...what could this be? I am married an am ttc. i am also stuffy and my tongue feels like i hate something hot and now its burned or something. i think my body is having issues or something. i also keep feeling like i have to use the bathroom like constipated.
