Mazal tov on your marriage.
In general, there is no medical reason for routine douching. Bathing and showering are sufficient for maintaining hygiene. The fluid in the douche could change the natural balance of secretions in the vaginal canal, which generally is not desirable. Furthermore, the douche apparatus can irritate the vaginal lining. Therefore, the best advice is simply not to continue douching.
If there is a particular reason that douching is recommended for you by a medical professional, it should be done carefully and gently, and should be avoided during the
shivah neki'im.
