I just recently had a miscarriage caused by high blood pressure. I want to try again, but i am worried that taking any medication while pregnant will harm the fetus’s growth. My doctor told me that i will continue to miscarry without the medication, but i am very worried about any effects to the baby. What is the safest blood pressure medication to take while pregnant and have there been any studies to prove no abnormalities. I am very worried. Please can anyone help. Thanks.
