You can leave it in for up to 12 hours for your period but for TTC I left mine in for about four hours with DD. This cycle I left it in for 6 hours yesterday and will be inseminating again tomorrow and I'll leave it in 6-8 hours I think for good measures!This sounds great. How long do you leave it in for after bd? With hubbys work onlu chance we get to is during the day so for me afterwords i lay for a bit then carry on with the day eg looking after my son cooking. So if you bd afternoon would you leave i in until bed time or over night?ive heard of soft cups just never thought of using them for baby making lol
