Good afternoon, mamas I’m 12 weeks pregnant; I had my first ultrasound at 7 weeks. The pregnancy is going normally, but I’m not registered with prenatal care. I plan to have two ultrasounds and the first screening in the next few days. I’m wondering which medications and which vitamins people are taking at this stage. I’d be grateful for any feedback.
