extreme tmi below,

but i’m 22 weeks pregnant and my discharge is chunky, ranges in yellow/greenish colors but no odor at all or no fishy odor. some days i’ll have a sour odor but not extreme fishy odor like i hear bv or a yeast infection comes with. i don’t have any irritation or burning when i pee and i’m not irregularly itchy at all. my ob won’t run any tests bc he thinks it’s normal. what do you think? i’ve had it my entire pregnancy. super heavy too, like changing my pantry liner every 3 hours or so.
