<img src="i/expressions/face-icon-small-confused.gif" border="0">Hi there, I am a 36 yr old female with CF and I am wanting to have a baby. My questions are as follows. I have read a few topics in here having to do with Robitusin medicine. How often would you take this? Would you take it like you would take it for using it as it says on the label or would it be takne differently? and having CF our menstral cycles are different so how do you know or how would you find out when your ovulation time is? Thankxany info will be greatly helpful
