Hi jacqui,
i wanted to tell you how very sorry I was to read that you weren't pregnant after thinking that this might be it. How incredibly disappointing.
Have you considered using a herbal/homeopathic fertility treatment? A properly formulated fertility remedy can be used in conjunction with traditional fertility treatments and works to correct hormone imbalances underlying unexplained infertility.
Also, here's a very interesting little tidbit: there is new research that shows how crucial the female orgasm is to the process of becoming pregnant. During orgasm, the cervix essentially "slurps up" the semen and brings it inside to find the egg. So make sure that you orgasm after your partner rather than before, and if you don't have an orgasm, do what it takes to give yourself one. Here's one link you can look at on the subject:
