Ask your doctor about femara. It is another medication that helps trigger ovulation. It works better for some women and has less impact on cervical mucous.
You mean after the egg is released you did BD and it still didnt work? hope there are no sperm issues. and also hope you did aggressive BD during egg release. and your doc might have tracked when you are releasing and all that.
on clomid, you may release only 1 egg, but if you use some injectables such as gonal-F, you may release multiple eggs then,
or you could try IUI. if nothing works, only then we move on to IVF. meanwhile, i dont think it is easy to comment on fertilization.
good luck.
