From what I've read, you can take it while ttc, but you have to stop at Ovulation because it can make the uterus contract, thus making it difficult for the pregnancy to stick. Then you can resume again once af shows, or at the third trimester if you get your BFP. This is my 4th cycle ttc, and I used the tea for the first time this month. I'm currently 10 dpo. We'll see...
