Hi i am 24 years old . I am pregnant 22 weeks now . I have an abnormal discharge during my pregnancy. The third time of the abnormal discharge i get tested. And the results found bacteria diplococcus gram negative. So my husband get tested too with his urine. But the results found out nothing. I have been monogamous on this relationship five years. I don’t have sex with anyone except my husband. How come i am the only one who get infected ? My gynecologist told me its possible get it from public toilet because during pregnancy immune system is weak . Is that true ?
