psych meds

I am currently 11 weeks, a little before I became pregnant I told my Dr that I wanted to have a baby, so he readjusted my meds. I am still taking my meds as prescribed but I am very nervous about miscarriage, birth defects and mental issues. I know I am only 11 weeks but I love my baby so much already, all I can ask for is a happy and healthy baby. What should I do? Please help me😔😔
