I'm 13 weeks
pregnant. From yesterday my doctor prescribed
calcium and iron tablets as the second trimester started . Till now I was taking folic acid alone . Last night I took a calcium tablet . This morning i couldn't eat food and felt like vomiting . I had one orange juice and took an iron tablet. After one hour I vomited.. but some were black liquid . It tasted like a tablet only . Still I'm afraid whether black vomiting is serious or because of my new tablets . Please help
