Unplanned pregnancy

I’ve just found out im pregnant with my 3rd child im 37 years old and barely cope with the 2 I already have and working full time
Hubby does not want a third child at all we are finally in a good financial situation and have brought a nice home and feel settled in our careers.
I don’t want another baby but I am petrified of having an abortion I don’t know what to expect or how to even go about it
My mental health isn’t exactly in the best state and I am worried that the abortion will add to more mental health issues later down the track but i also know having a third baby will also affect my mental well-being
For those that have had an abortion how did u cope with the guilt afterwards?
Or did u have a third baby and everything was ok?
