While i was peeing, i noticed three pea size lumps of white discharge had dropped into the toilet, ive had a fishy odor for the past 4 days. and just got off antibiotics for a possible UTI. my husband and i have been trying to get pregnant, my period ended the 11th of this month and we ve been doing the deed everyday since then. Could i have an STD or could i possibly be pregnant? i would like to know what your ideas are before i take another pregnancy test, i just dont want to be let down anymore.
