How long

So cycle sisters, how long have you all been TTC for? And do you have any children ??? What signs do we need to be looking out for.
Also I came across Angus vitex (I think that's how it's spelt) any of you heared of this or used it? I think I'm going to try something on my next cycle such as this or pre seed. That's if I don't my BFP this month. Also another question (sorry) what parental vitamins do you take ? I came across a post were a lady wasn't sure about some brands ????
