Just wondering if anyone has any experience of using mooncups? I'm thinking of buying one and would be interested in any feedback. I'm not keen on the amount of chemicals used in tampons and pads or the fact that they end up in landfill. I spend a fortune every month on sanitary products and often leak with tampons as my bleeding is so heavy.

Any comments would be much appreciated x

Hi Scribble, I've used a diva cup for 2 years now. They take some practiced to put in & out but Id never go back to tampons or towels. You can buy different sizes so you should be ok even on a heavy day. I have never had a leak even over night but the trick is to make sure it is around your cervix. Give it a try you will love or hate them x


Thanks! I'll try it and see how I get on x


I have used a mooncup for years take a little while to perfect putting it in but find it brilliant and obviously environmentally much better. Someone posted about them on here last night and I found this brilliant website with reviews of all sorts of stuff which I never knew existed. 😳http://reusablemenstrualcup.com/category/menstrual-cup-comparison/

I do leak sometimes with it but not as badly as with tampons and good at beginning and end of period so you not removing tampons with few drops on I really worried about the tampon fibres too. You also get an idea of flow too to tell gyne. On that website lots of reviews of washable towels and tampons weirdly and stylish period pants :) it's not selling anything just reviewing so quite interesting.

There was a thread about this recently. There is some controversy about menstrual cups with suggestions that they may be implicated in the 'cause' of endometriosis by encouraging retrograde menstruation. But this would be an outdated idea because it is now known that endo is a multifactoral disease involving abnormalities of the endocrine and immune systems as well as the well known gynaecological issues. The trigger for those who develop it is not known but it is clear that something happens in women to cause the transformation of potential endometrial tissue into endo that doesn't occur in women who don't develop it. It is thought most likely to be an immune system fault. So for women who don't have this unknown predisposition then retrograde menstruation (which is common in women generally) will not cause endo and so back flow through the use of menstrual cups will not be an issue. Perhaps I should qualify that with 'probably' because ultimately we don't know the many means endo may have at its disposal to achieve its ends. I suppose in someone who already has risk factors such as familial links and a compromised immune system with allergies and intolerances, to have their pelvis regularly flooded with menstrual debris this may overload the white blood cells sent out by the immune system to mop it all up (macrophages) and tip a balance. Peritoneal macrophages are significantly involved and altered in women with endo.

But by the nature of this site we are talking about women already with endo. In my period days there were only pads and tampons but from what I understand from the literature about these cups they can be kept in for quite some time, positioned in the vagina or tight around the cervix like a diaphragm cap, holding back blood to be emptied as convenient. It must follow therefore that for someone with a heavy flow blood must back up and pool in the uterus until released while more blood continues to be produced alongside any cramping the woman might experience. It seems highly likely then that retrograde menstruation will occur in such a scenario.

Let's consider why birth control is given to women with endo. It is to lower oestrogen levels in an attempt to suppress endo growth but also to stop or reduce periods to avoid retrograde menstruation as well as to ease pain. Women having excision surgery are usually advised by their specialist to take contraceptives afterwards to stop or reduce menstrual flow to minimise the possibility of new endo from retrograde menstruation. So why would anyone with endo actively use something that encourages it? For women with the lightest flow who can be sure to empty a cup well before it is full then it may be a safe consideration. But for anyone with a flow such that blood is held back in the uterus then I wouldn't go near them.

It has been said in some discussions that surely tampons are just the same. But of course they are not. There is one significant difference and that is that these cups are presumably intended to be watertight and firmly held in place. Tampons are, as we know, soft and absorbent and once fully soaked they will allow blood to flood out and will often fall out under their own weight when flow is heavy. Also we are educated to know not to leave them in for any length of time. The chances of blood backing into the uterus with tampon use would seem very slim.


Thank you all for your really helpful comments. I think I need to do some more research and give it more thought ... xx
