Instead Cups (Softcup) holds rather than absorbs fluids, you should be able to wear the Softcup twice as long as a tampon up to a maximum of 12 hours.

What is Instead Cup - Softcup?

Instead Cups are a unique disposable period protection product that is worn internally and collects, rather than absorbs, menstrual fluid.

Some surrogates have told us that they have used soft cups to hold the sperm closer to the cervix and optismise chances of conception. You can use these in conjunction with our insemination kits for optimal results. 

We would love to hear your opinion if you have tried these.
