I had a miscarriage in my previous pregnancy due to an incompetent cervix. I am now
pregnant for the second time and currently in my 15th week. Recently, I experienced excessive white vaginal discharge, so my doctor performed a manual vaginal examination by inserting a finger to check my cervix. She also inserted a vaginal speculum to examine my cervix. The following day, I underwent a transvaginal scan, which showed that my cervical length was 3.6 cm.
Given my previous history of cervical insufficiency, I am worried. Could the manual examination or insertion of the vaginal speculum have caused my cervix to open or caused any damage to my cervix?
