I'm scared

So I'm a FTM and currently 38 weeks pregnant. My husband and I are thrift/dollar tree shoppers. We're not fancy in anyway to say the least. Anyways, some friends came over and had dinner well I pulled out our plates and cups and my friend flipped saying that these plates and cups contain lead. They are dollar tree plates and cups made from china. She freaked me out with all this and now I'm up worrying and cannot close my eyes. All I want is for my baby to be healthy and now I'm scared that I was using these which is something I could have prevented if I only knew. What you pregnant moms think? I'm really scared
