This is a tough decision that many women have to make during pregnancy or while planning a pregnancy. The best advice I can give you is to talk to your health care provider immediately regarding your situation. The risks and benefits of taking any antidepressant medications need to be weighed carefully for each individual. You should mention that you have been experiencing relapses of your symptoms, so not taking your medication may not be the best option for you even though you may be pregnant. In fact in some situations you may be putting your health in danger.
Often as women our first instinct is to do anything to protect our babies, even suffer through miserable symptoms in order to protect our babies from the possible side effects of medications. However, it is important to consider that your baby needs a mommy that is healthy physically and emotionally. Again, I urge you to contact your healthcare provider today for their advice regarding this and all medications you may be taking.
