Feeling very sad mom being harsh about getting pregnant

Heyy guys so please be nice in this post I'm just feeling very sad my mom is very supportive and loving but also very harsh and critical at times I just got off the phone with her and she just finished telling me (we are in the middle of fertility treatments and have been trying for two years with a miscarriage) that she doesn't think we are rich enough to have a baby and then laughed and said we'll I guess poor people can have babies too it just made me so upset sure we are not making 100 000 a year but we are stable have a nice place for the baby to grow and have been wanting this our whole lives she then proceed to yell me if I don't get a raise soon I should find a higher paying job which I know she is just looking out for me but it makes me really upset that is pretty harsh and not fair especially when my dad was rich enough she didn't have to work throughout their marriage and doesn't understand the struggle (not knocking stay at home moms i would kill to be one! I just don't have the opportunity) I just need some kind words and reassurance :(
