This is my 4th pregnancy and I want to tie my tubes since I'm having a c_section but my SO says he wants all least one more!!!

Now the situation is I already have 2daughters from a previous relationship ,and last year me and SO lost our daughter due to chromosome disease and I am now 21 weeks pregnant with a boy!

I just don't want to put my body thru another pregnancy I will be 30 next year and I want to enjoy the children that I already have.

Idk what to do?!

Any thoughts???
