My SIL uses the spray around her baby (now babies) and while she was pregnant. I think its pretty safe. But I haven't used it yet. She really likes it, or at least she is still using it.
I'm not sure about the green works line, but there are a few things you can find in your home that are green and cheaper than those green products you buy at the store. Here's an article that explains it all. https://housekeeping.about.com/cs/environment/a/alternateclean.htm
I've used it and it works pretty good. I have no idea if it's safe for pregnant women though. I also make my own cleaners w/ some recipes I found online & those are definitely safe. Try the link above.
