Do trich or bv cause thick yellow lotion like discharge with fishy odor sometimes brown or bloody & lower stomach feel like I been excersing?

May be BV. Bacterial Vaginosis is usually accompanied by a fishy or ammonia smell. It can be treated with a number of medications. It isn't usually accompanied by blood or lower abdominal discomfort, so it would be important for you to be evaluated by your health care provider. Good luck. LGromkoMD.
See remark. Trich infection cause the type of discharge you are describing. !st :try douching with warm water for cleanliness Next you need Flagyl ,something I can't prescribe in our setting.If you don't have a doctor,of insurance,please visit a city/county local health clinic they will give you the treatment. Best of luck.
