Not sure what to do?

So im 17, ill be 18 in june. Im pregnant and due in July. My job doesnt offer FMLA because i wont be there a year yet( im two month shy of a year), they said they might offer me only 2 weeks paid after the baby. My boss was talking to me about unemployment but i looked into it and it states that you cant just be “pregnant” because physically you cant work, so they talked about short term disability. I dont know what other options i have or how to go about applying for it so im all set when the baby comes. Could you guys please tell me if there is any more options or how i would go about applying for STD (short term disabillity)? I live in PA btw if that makes a difference.
