I had a fishy smell for a whole week or so out of every month and it was for about 7 months I had no idea what was wrong but it got real bad to the point I went to the dr they said I had a bacterial infection and a yeast infection they gave me the 500mg 7 day treatment 2 times a day to take and a single tablet for a yeast infection although the antibiotics made me very sick I did manage to finish it all and get it taken care of and I now have NO fishy smell at all and I didn’t know if I needed to go back to my obgyn to make sure it’s gone because they never told me too and all my symptoms are gone... we are 5 months ttc and I didn’t know if it would affect me getting pregnant ...
