Most of the medications for mycobacteria are used to treat mycobacterial vaginitis. If the medication is put vaginally, it has no effect on pregnancy. Whether it is oral medication for mycobacteria or vaginal medication for mycobacteria, it does not have a great impact on the development of the fetus, so there is no need to worry too much. However, mycotic vaginitis is very easy to recur, and it is more likely to recur during pregnancy. Therefore, after pregnancy, you must pay attention to the hygiene of your vulva, wear cotton, breathable underwear, wash your vulva with warm water every night, and expose your sanitary products to the sun to avoid the occurrence of mycotic vaginitis.
