Getting my tubes tied?

Cece

So I have a daughter from a previous relationship. She will be just under two when my son is born. My mom wants me to get my tubes tied because she says she doesn’t think I need more children after two. Now mind you , my daughter was planned after six years together with her father. While I was pregnant he cheated as we split shortly after she was born when I found out it was with my bestfriend. My current boyfriend and I have been together a year and this baby wasn’t planned but we both couldn’t be happier and it had actually made us closer. My mother thinks this is enough children for me and says she can’t stand me when I’m pregnant because I am bipolar and I refuse medication while pregnant. She had me believing I should get the procedure. My boyfriend says he thinks I shouldn’t. He says we might want more some day. We are both still young. I’m 24 he is 26. He says I might regret it. I don’t know what I should do in this situation. Any one else considering this option?
