Hello-
While tampons and pads are the most mainstream feminine hygiene products, its good to use menstrual cup. Rather than absorbing menstrual fluid, menstrual cups are inserted into the vagina to collect the blood until full (which usually happens after eight or nine hours).
Menstrual cups are easy to insert, wash and reinsert. They're comfortable, nontoxic, reusable, making them good for you and for mother earth! I recommend them to my clients, all of whom report back with positive feedback.
