Deep regret from planned pregnancy (tw abortion)

Ive always thought I wanted kids, going so far as to talk about parenting strategy, what my baby shower would be like, designed the nursery in our minds, have names set. It’s been THOROUGHLY discussed. I just found out I’m pregnant after trying one time with my husband. I was surprised that my first reaction was dread, we made a mistake, we ruined everything, I don’t want to do this and not happiness or excitement. I expected to feel scared but not like this. I feel such deep regret and this want to go back to last week when I didn’t know and was happy. I looked around on this sub and some others for insight but most people posting with this feeling are also feeling first trimester sickness, which they think is a factor in their feeling of regret and depression. And most responses are about hormones making you feel regretful and how everyone has “days” they think what have I done.. I do not have any symptoms and I still feel such deep regret and depression every second. It’s only been two days since I found out but I don’t want to eat or shower or get out of bed. My only solace seems to be in the tiny moments I forget for a second I’m pregnant while scrolling or watching tv. It also doesn’t seem right to follow through with a pregnancy based on the assumption that my feelings aren’t real and they’re just hormones. I generally have mood swings from hormones during my cycle so it’s not out of the question, but What if they’re not? And it’s too late by the time I realize that I should’ve just trusted myself. I love our life now but I feel like I’m taking away my husbands future if I terminate. Like I’m taking away his baby or something and I hate myself for doing that to him.

If you made it this far thank you so so much for listening. I’m not sure what I’m looking for, maybe just some insight or comforting words. I feel like my heart is breaking.
