To me, it seems like you are coming off with excuses in reading your response.
Are things hard for you with no jobs, no savings and pregnancy ? Absolutely
Do you seem hell bent upon making sure you do the best for your baby given your situation ? Not Really.
Here is what I would do if I were you and for me there would be no ANDS/BUTS
Call Planned Parenthood and understand what they can do for you on the phone before you go. Also make sure you understand what paperwork they need to make sure you are unemployed and qualify for their services free.
If you are living with your bf then have him drive you him picking up the gas money cost should be a given. If that seems hard barter it for a birthday /anniversary present. If he is letting you live and have food then he seems generous enough to drive you to the appointment.
If you have no money, find a helping/ cleaning/baby sitting gig you will need some money regardless of your job situation if you are pregnant and have nothing.
Confide in a family member or friend that can help with some of the small things.
If you are a member of a church then see if they can do some important things for you.
Get rid of some of the victim mentality that may be setting in and instead motivate yourself to explore every free/low cost alternative available even if it requires being a little creative or going out of your convenience zone.
Good luck! Have a H&H9
