Hello i'm having pregnancy symptoms even though i may have only conceived a week ago. It is too early to take a test, so i will have to wait to find out for sure. In the mean time I am taking anti depressants, and mood stabilizers. The medication I am most concerned about it Lithium, because my psychiatrist said make sure not to become pregnant on this medication. Should i stop taking it, it don't want it to harm my baby if I am pregnant.
