Girls, hello. I recently saw a gynecologist, she prescribed me D3 calcium and cardimagnel. When asked why cardimagnel, she replied that it might rise blood pressure in the evening, although my blood pressure is always normal. Is cardimagnel harmful during the second trimester? I was taking Prenatal (multivitamin) before. She said folic acid can be stopped.
