I am over four months pregnate, and having a lot of discharge that has a foul odor. I have been tested for stds and infections and nothing came back. I am very concerned. My underwear are ruined they smell even after washing and after a day at work, the odor is on my pants as well. I am showering everday, wearing panti- liners. I don't know what else I can do. This is very embarrasing, I am always wondering if someone else can smell me. Please, please help. I don't want this for the next five months. What can I do?
