I have already considered all other factors in trying for a baby and want to know if any of my tablets may hinder my chances? could you take a look?

Meds and fertility: I don't know what cerelle is, but chronic and or heavy use of Codeine or any narcotic can affect fertility by suppressing gonadotropins from the hypothalamus and pituitary - thereby affecting the ovaries. I always tell young women that it is best to be on the lowest amount of medications possible for fertility and pregnancy.
