I thought this thread might be useful for anyone who's thinking of taking AC or anyone who has irregular periods & needs some help. I started taking AC in Nov. I didn't have a period for 6 months after my mc, then it finally came but didn't comre back. So I found out about AC & thought what harm can it do? It's a herbal tablet so it doesn't do anything to you. Sure enough after taking it for 2 weeks I got my af!! That cycle lasted 63 days, god knows how long it would have been if I hadn't taken AC. My last cycle was 40 days, I'm now on cycle day 1 so hopefully it will reduce it significantly again, I may even have a 'normal' 28 day cycle!! If you have irregular periods I would strongly reccommend taking agnus castus. I'd love to hear other peoples experiences of AC.
