A woman can swim during a period by a using tampon to avoid bleeding on the swimsuit, as stated by KidsHealth. Some women may be tempted to use pads, which may not be effective while swimming.
Chances of pads falling off while swimming are high especially compared to tampons. While pads may work, they can become heavy and uncomfortable while in the water. A tampon is inserted into the vagina. It has a soft material and a string to allow a woman to remove it easily. The applicators can be cardboard or plastic, to allow a person to choose one that she likes most.
