Just wondering if anyone can comment on how vitex affected their luteal phase? I've only been taking it one month, and started because I've had such intense pms symptoms the last few months. It's definitely helped with that already. I've read it may also lengthen your luteal phase- but I didn't really need help in this area since mine is naturally 15-16 days- it feels too long already! But, AF was due Sunday or Monday and has yet to arrive. I'm wondering if vitex has already affected my LP? I started with cramps yesterday, and a tiny bit of spotting (may be due to pap smear I had yesterday), but no AF. ???
