Hey, please don't be hard on yourself! With my last DD, I refused meds all together, despite being very low in mood and very anxious. I got so unwell mentally after her birth and then didn't take meds for a few weeks.. then they took a few weeks to start working.
They generally day 2 weeks to start working, 4-6 weeks until they're in full effect.
I'm currently pregnant with #4 and like you, I wanted and tried for this baby and I'm honestly not that happy about it! It's bizarre. But hormones seem to be sending my brain funny.
This time I'm staying on my meds, so hope to do better.
You will bond with your baby. You will. It might be whilst they're growing in your belly, it might be the moment you see them, it might be that you realise it slowly in the days and weeks after they're born, but you will. ❤️
There are side effects to being depressed when pregnant too. So in my opinion it's better to be happy and pregnant, than sad and pregnant.
Also if you speak to your midwife, she will be able to signpost you. I've been referred to a perinatal mental health practitioner for support.
Take care xxx
