yellowish discharge

i recently have pale yellow colored, creamy (and kinda clumpy too), smells a little bit fishy—kind of discharge. what i concern about is the amount of discharge i produced in a day. it even makes my pants really wet.

can anyone help me? is it yeast infection or gonorrhea?

my vagina is not itchy, and i don’t have any fever. it feels like a normal discharge, except it’s a lot and when i have sex it’s painful in the beginning.
