TTC and anti-depressants

I've been referred to a Psychiatrist because (shockingly, after a year and a half ttc) I've been diagnosed with depression. My spot is today and my Dr has already suggested that I would highly benefit from a prescription anti-depressant, but that seems counter-intuitive when I'm ttc. Is anyone else here on an anti-depressant and willing to talk about it? Does anyone know which pills are pregnancy-safe if I do become pregnant (as I keep hoping)? Thanks in advance!
