Baby making is a science. No spells can make the womb hospitable, sperm swims faster, viable egg whatever the issue it may be. You are better off seeking real professional help right off the bat and pinpoint the actual issue rather then dump money on something that is not even proven to contribute directly to fertility. You might end up spending more money and more frustration and stress than originally intended which to lead to more delay in conceiving.
You might have heard stories from baby forums already about how couples try and try and nothing and only was then able to conceive after they let it go. Stress is a major factor but it also depends on your age, the physicals of both parties etc. Time the deeds to ovulation prime times and if all fails, speak to your family doctor and do a thorough workup to make sure both are in healthy shape to make babies.
Hope that helps.
