Abortion over 30

I’m single, 35, and faced with an unplanned, unwanted pregnancy. This is my first time ever being pregnant. I do want to be a mother, but my current situation - inconsistent job, unstable income, unstable relationship with the father- are forcing me to consider eliminating the pregnancy. Is there anyone out there, particularly over 30, who’ve been faced with this? How did you chose? Is there any advice you can give? Am I risking not being able to conceive after having an abortion at my age?
