hi pawre
i would advise any soya products in whatever form from the info i have read.
as to barley, spirulina, unfortunately i can't help. perhaps a web search might produce some information for you? but it sounds as if it might not be the best thing to consume if contra-indicated in preg.
as jane12 says, holly c, is an expert on teas. she won't mind if you PM her direct. she is away this weekend i believe, hence she probably won't be able to respond until next week. i too seem to recall that raspberry leaf wasn't advised during ttc. i think another tea beginning with "r" is a good substitute, sorry cannot remember the correct name, but holly definitely knows. i'm not a tea or coffee person, not a health thing, just prefer water really.
sorry my knowledge is only as good what directly affects me. you could post a thread specifically re barley and spirulina and/or the tea.
good luck
