TTC taking Vitex

Sooooo! I took Vitex towards the ending of August , and AF came 14 days later ,I was so HAPPY because I'm irregular lol.. So now it's October, and I'm waiting on AF 🌾👀🌾 . My period should've appeared this week. I took a PT the day AF was suppose to appear and it was a BFN . I have my fingers crossed for a  BFP by next week. I sure hope so. I'm still taking the Vitex , until I for sure know I'm pregnant , cause I'm thinking maybe AF is late. Time will tell , I'll keep you ladies updated.
