Feeling overwhelmed

Ok.. so this is my second post for the day cause I’m feeling hella overwhelmed.

I have wanted to be a mum for as long as I can remember. We’ve been trying for a few years and it’s finally happened and I’m already 6 weeks. But today I just had such a heavy feeling of “what the fuck am I doing? What have I done?” And I just can’t get past it. I thought I wanted this and I have pined over it for so long and now, just today, I just have this crushing feeling that I don’t want it anymore and I’m very seriously considering my options. Has anyone else felt like this? How do you navigate that feeling?
