My husband and I have been trying to conceive a child for over two years. I’m 38 years old and about to undergo fertility treatment. Is there any herbal remedy you could recommend to boost my chances of conceiving?

I have recently found out that I am pregnant — a surprise, as I was on the pill. I want to make sure that I am taking the right supplements for a healthy pregnancy. I have stopped taking my usual vitamins and am reading up on healthy eating options. What would you suggest?
