Please advise) I'm at 7 weeks. My therapist, without any tests, told me to take Iodomarin and to come register for prenatal care in two weeks; Should I wait for the gynecologist visit and to have tests done or start taking Iodomarin? I'm taking folic acid, but I'm doubtful about Iodomarin, and a bit unsure about the doctor too.
