Hi! It is fine to start working out now! Three to four weeks after vaginal surgery is fine. Please listen to your body though and don't over do it!
This a normal finding postoperatively. A small amount of blood is expected as the femilift procedure works by exfoliating the dead layer of vaginal epithelium. Nothing to worry about!
Femilift as a treatment for atrophic vaginitis may help your yeast problem. Chronic yeast infections may arise after menopause as a result of vaginal dryness as the normal vaginal environment changes. Thus correcting the dryness may cure your chronic yeast.
