Hi mommies. Please help me out. I went to a Gyna today and all he did was the scan and asked me random questions. Is he not supposed to perform a variety of tests and prescribe or give me supplements? He seemed to hurried for my liking. Am 13 weeks pregnant and he said he'll only do the tests at 20 weeks. But the app I downloaded says the opposite. I have a checklist that I went through and I haven't ticked a thing for the whole of the first trimester
