hi Kingy,
if you google for a course near you you will hopefully be able to book ontoa maternity reflexology course.
would you feel confident doing the treatments from advice from a book? If you feel capable and confident at it, then its up to you really, as long as you're fully trained in reflexology and have a good understanding of the repro system, endocrine and lymphatic.
I'm co-ordinating a Maternity reflexology course in September but its up in durham. You are welcome to a place if you want it.
