I was treated with for trich in november along with partner one treatment 2g we abstained for 10 days. i hadnt had a single symptom since then. then 2 weeks ago i started having really watery thin white discharge no smell no itch? could it be trich

Trich? Other STD?: Single dose treatment of trichomonas with metronidazole works about 80% of the time -- i.e. 1 chance in 5 it didn't cure you. (Upcoming new official recommendations will be to treat trich for 5-7 days.) So this might be trich. On the other hand, other STDs also are likely. See a doctor soon for retesting for all STDs. Good luck.
