spanner after all this is over you'll look back and think "Why did I fight ADs for so long??"
I was on them for 4 years and though I've been off them for 10 years now, the memory of how they literally saved my life is never far away. I have been keeping a close eye on my anxiety levels and would have no hesitation in taking them again, yep, even during pregnancy.
And after baby is born I'm going to be hypervigilant about PND, and will gobble all the medications in the world just to ensure I'm able to function as a mum.
Think of it this way, you are taking steps right now to ensure you're carrying baby in the healthiest way possible. You're taking care of yourself, and in doing so, you're actively working towards a positive pregnancy. I think you should give yourself a pat on the back, tbh, as you're being a proper Mum by being responsible about your health. There's nothing childish or selfish about going "right, I need to do this". On the contrary, it's a very level headed and mature reaction, and is an intensely difficult point to get to when your anxiety and depression are whispering in your ear that to seek help is weak.
I began to think of my depression as that Bad Angel on one shoulder, whispering terrible things, trying to undermine you in every way. "Look at you, you're a mess" etc etc etc. It was only when I started taking tablets that that voice started to recede. Before, it was so loud you can't even think! Or sleep, or eat....just whisperwhisperwhisper all the time.
So I'm proud of you, and I know one day you'll look back and be proud of yourself too.
