Blood found on mooncup

11 January, 2016


I've been having bleeding that lasts more than 5 days. I've been showing my mar'ot to a rabbi who has been telling me that I can only get a clean hefsek tahara on day 7 or 8. I saw on the yoatzot website that a mooncup can help to shorten bleeding time. I'm just wondering, is a mooncup mekabel tum'a? Normally I will not use a tampon until I am sure that I have a "flow", as I do not want to become ta'mea too early. If I were to use a mooncup while I am still only staining at the beginning of my period, would that blood make me ta'mea? Or could that blood count as a ketem found on something that is not mekabel tum'a, not making me a nidda?


The leniencies of ketamim (stains) apply only to stains found externally. Once an object is inserted internally, any blood found on it is not considered a ketem, but is comparable to blood found on a bedikah. This is why any blood found on a tampon will make you niddah; you are correct in not using one until you have a "flow." Similarly, any quantity of blood found on a mooncup will make you niddah, independently of whether it is considered mekabel tum'ah. You should not insert any object internally to contain the bleeding unless you consider yourself niddah already.

There are other methods of trying to shorten the bleeding besides the mooncup. We have received reports of taking large doses of vitamin C (some specifically recommend lemon juice, although pill form likely works as well) once the bleeding begins, as well as alfalfa (leaves/sprouts/seeds). There are herbal remedies that claim to reduce the bleeding (such as shepherd's purse) but we only recommend their use after consulting with a healthcare professional (conventional or alternative).
