Although it seems that soft cups can be hard to get hold of in the UK – not many of the pharmacies seem to sell them and they are not yet in the big supermarkets, you can get hold of them easily enough by mail order.
Soft cups are on sale at Amazon and you can buy them in packs of 6 or 24. Each soft cup is wrapped individually for hygiene purposes so you can just use them whenever you like. Soft Cups are disposable although some ladies do you reuse them by washing them thoroughly in boiling water, although this is obviously not recommended by the manufacturers.
Soft cups can be left in for up to 12 hours so if you are using them for TTC then you can insert them say late at night and remove them in the morning and you will avoid the ‘leakage’ scenario that can often occur. Also use them during the day for even more secure holding of the sperm next to the cervix.
