Loving all the moans! Can totally relate to what you're both saying - especially what you said Clanger about if only we could know when it would def happen so we could just get on with life and stop being such mentalists about the whole thing!
To answer your question, softcups are designed for AF - a bit like those mooncup things - but have been used for ttc by some people. Basically it's a flexible ring with a pouch that you can slide in after bd-ing to keep all the sperm where they need to be for a little bit longer than usual. Or you can put the sperm straight into the pouch and slide it in - the way it is designed means it keeps everything close to the cervix, so there is a good chance of them swimming through.
It takes a little while to master (particularly removing it the next morning) and I don't think I'd want to use it for AF, but now I've got the hang of it I've used it on and off after bd-ing and at times to to the whole self-insemination thing. There was a whole thread on it somewhere and seemed to have quite a few successes. Nothing has been scientifically proven, but I don't suppose it hurts any.
So I've been using Fertility Friend to record my temps and they seem to think that I ov'd on Monday - this was the other day we managed to bd, so we may have caught the egg. Dunno - depends what time I ov'd I suppose (I'm not one of those women who feels it unfortunately - thought I did once, but it was just indigestion

). My erratic sleeping means that my chart is a bit all over the place, but they seem to see a pattern even if I don't. It also times with my CBFM peak days, so here's hoping we caught it - if I managed to get the sperm in with the softcup that is!
Got a big work party tomorrow, and I don't think I can get away without having a drink without drawing serious attention and tricky questions to be honest, but will try to keep it to a minimum!
