Worried

Ho

I had a miscarriage back in July. Found out I am pregnant again, due July 2018. I've been taking some herbal supplements from my job (researched based nutrition company) and just learned this morning that herbs may cause a miscarriage. I am stopping these supplements now (took some this morning prior to being informed). Now I cant help but think I may cause harm. I'm only experiencing tightness in my abdomen, metal taste, and swollen/sensitive breasts. Why can't we just feel like everything is going to be Okay? Already worried in general.
