I am 24 and have had this issue for a couple months now since February or Jan. Which I’m a little concerned about. I suspect BV could be the cause, yet the test results I received recently were negative for BV and other conditions I’ve got got tested twice and everything came back negative for any stis or infections. Idk how to get rid of this odour and I fear it might affect me and hinder my chances of having children in the future if not treated. It’s an onion smell and it leaves a yellowish/brown colour in my liners. Have any women here gone through the same issue and found a solution?
