Ttc & stopped takin fluoxetine. is there any way of distinguishing the difference between recent emotional changes being from early pregnancy symptom?

Please follow up: Depending on why you were taking the fluoxetine, you could have resurgence of symptoms. Early pregnancy by itself does not cause depression, anxiety disorder, panic attacks, etc -- but it can exacerbate underlying tendencies. Please follow up regularly with a psychiatrist to make sure you stay as healthy as possible in your pregnancy, & to monitor for any issues so they don't get worse.
