baby budgeting!

I'm not even positive yet that I am pregnant. My period isn't due for another 6 days or so, however I've been pretty irregular. I kinda just have a feeling I am with some of the symptoms I've been experiencing. I'm scared tho my bf and I have been together almost 3 years and we love each other unconditionally and would love our child together. Although I really don't have a great job and he only works part time right now because he's going to school for physical therapy. I'm just so worried that financially we will really struggle. We don't have our own place right now, but I would truly love to get our own apartment I just don't know if it would be possible to save enough for baby and a place to live. We aren't babies by any means both just turned 27 we just feel like we are so behind. Just wondering how some people were able to budget for baby TIA!
