I am pregnant. My period was missed since last month 20/03/2020. I also did pregnancy test at home. And I got positive results. I consulted from a gynaecologist over phone and she advised me to take vitagreat and susten sr 300 mg tablets without doing any test. Kindly tell me is it fine to take these medicines on regular basis or should I do tests to take these medicines that I need them or not to avoid any side effects if any? Also tell me when should I go to doctor for any test or ultrasound?
