Mild vaginal inflammation has little effect on the foetus and can be cured. Severe vaginitis that is not treated promptly can cause intrauterine infection, premature rupture of membranes, and even premature birth. The choice of medication for treatment should be under medical supervision and used after the doctor has fully communicated the pros and cons with the pregnant woman. It is important to visit the obstetrics and gynaecology department of a regular hospital and not to treat yourself by reading advertisements.
