Hi again!

I second Tasha's comments. In the past I've had irregular cycles and fairly long too (after being on the pill for 15+ years!) but they've settled down a bit the last couple of months, I think mainly due to two things - Vitex (chaste tree, which you mentioned) and acupuncture.

Have you thought about charting your cycle to see when you get fertile signs and how your cycles vary? Might be handy - there's lots of free templates you can download or you can join Fertility Friend. Can be good to keep a record to take to your GP down the track if you need to as well. Hard evidence!

Hope things settle down and best of luck with TTC.
