I feel pretty terrible

I had some tea tonight with my cousin, and it was echinacea tea. I wasn't even thinking about it, she gave it to me because I have a bad cold and I have laryngitis, and it was only after I was driving home that I was like, uh oh, I don't know if I should have had that. Came home and saw this post and found out that its not considered safe during pregnancy because it can cause uterine contractions. I am not having any cramping at all, so I am hoping I am ok... so worried now
