According to my pdoc Lithium shoud be stopped immediately if pregnant as it can cause heart defects in the baby. Also seroquel as not enough eveidence that it won't harm the baby. You must see a pdoc as soon as possible so you can work out what is best for you and baby. Good luck and Congratulations
