Hi laloo. I also have regualr cycles but 10 months later still not UTD. I hummed an harred over whether to try vitex or not. I decided no cos I have a really good cycle length and LP (luteal phase). People on here have said it is great IF you have problems with your LP & cycle length. I have read that some people here tried it and it stuffed up their great cycle. Other people said it just did nothing. I've read lots and my conclusion is that don't fix it if it aint broken! LOL.
If you do decide to try vitex, I have read that you must stop it as soon as your UTD. There's conflicting info whether or not you need to stop it after ov. If I did take it, I would probably stop it after ov.
Here's a link you might interesting to read...

I'm also trying a few new things this month like me and hubby are taking zinc as it seems to have worked wonders for a lot of people here.
Good luck and I hope it's not too long before you are UTD!!
