Has Anyone Gone On Or stayed On antidepressants while Pregnant?

im just curious about this, If you have anxiety or depression.. I find myself easily irritated and snapping at people and frustration can go from 0 to 60 in like 2 minutes.... Im stressed out with the usual fears, thoughts.And I have suffered from depression before. I had a health nurse say there are some medications for depression that are "safe" to go on while pregnant. Can anyone tell me if they have been on It an antidepressant and If it was okay for there baby. I know it affects your neurons, receptors ect.......and I dont take any medications other then gravol and occasional tyenol if a headaches really bad otherwise really healthy and I do not smoke or anything like that, So Im just curious if anyones Gone on them and How they found it??
