Pregnant and in university.

Started university in September then found out not long after Im expecting a baby in June. Its my first year of a 3 year course and I'm really struggling with what to do. My family are encouraging me to stay in uni which I would like to do however financially in Wales you don't get much help being a university student with a child. My partner has a job but not paying enough to provide for 3 people. I have a part time job waitressing but not going to be able to manage that on top of uni and the baby😔 my mother said I could live here with the baby but my step dad isn't over the moon with that idea and I don't want to cause arguments between them. Just need some advice has anyone else been in this situation? I'm from Wales 😔
