Hi Megan!
It couldn't hurt, I don't think, to take it. Only you can really decide that. If your hormones are level, though, I don't know if vitex would help. It's supposed to balance out the hormones (it's supposed to really help with progesterone). Maybe do some reading on it to help you decide? I recently listed about 10 links on another thread:
Vitex and the effects of taking bromocriptine for high prolactin levels
Go to the second last post; they're all listed there. Oh, and one other that's not listed:
chasteberry
I haven't come across anything negative about vitex so far. So it might be worth a shot. You never know.
I've heard some good things about False Unicorn Root (FUR) too. I just haven't done a lot of research on it yet. Maybe look into that one too?
Sorry about your loss. Wishing you lots of babydust and a BFP soon!
