Is it safe to take Chaste Tree supplements (Vitex) whilst breastfeeding? I have a 15month old who still feeds quite regularly - even though he is also on solids - and I would dearly love to conceive naturally this time without having 'help'. It's been 2 years since my last period, but just as I was starting to give up hope, AF came on Friday. Is vitex as effective as Clomid?? and when should I start taking it (if it is indeed safe)? Sorry, so many questions. Is there a higher chance of hyperstimulation too if you take vitex??
