Massallah pertaining to having a baby

As-salaam-mualaikum Mufti
I am 26 years old, I have a full time job and study. My husband also works but we cannot survive on his salary. I really want to have a baby but I am afraid that if I do, I will not manage financially if I have to leave work to look after the baby. Our parents live far away, so I have no help. I am on birth control. Im also waiting to get a medical aid. Please advise me. I really want to have a baby but I am also afraid.
Shukran
