I've heard of some woman starting right when they find out they are pregnant and some waiting until the second and third trimesters. I guess it just depends. when I was about 18 weeks along, I had a midwife tell me NOT to drink it until I was closer to my due date. I have not started yet (i'm 29 weeks), but I'm thinking of trying some out. I take a prenatal vitamin that has RRL in it and I just found that out. (i've been taking the vitamin since the begining of my pregnancy). Here is something I keep seeing:
1 cup of RRL tea daily in the first trimester
2 cups daily in the second
and 3 cups daily in the third
(I think i'm right on this)...
Just from certain things I have read, I think its better start drinking it later on, but thats just a personal preference. Just do your reasearch and decide whats best for you and your babe. Good luck!!
Everyone reacts differently to it. Some it will cause more contractions/BH and some it doesn't have much outward effect. My suggestion would be to try it and see. I like to take it as soon as I find out because it doesn't seem to cause any additional ctx/bh and it helps provide me with vitamins, etc and tones my uterus. However, I also start slow with one capsule and work my way up as the pregnancy progresses.
