17 too young to be pregnant?

I'm 17 and I will be 18 next month. My boyfriend is 18 and we've been dating for 2 years and I love him no doubt, not questionable at all. I don't have a job but I am currently looking for one, but my boyfriend has a really good job and gets enough money to pay rent, bills etc and still have money over afterwards for play (you get where I'm coming from.). We do not live together, he still lives at home, but we've worked out his wage and have decided not to move out together until I have a job and can chip in too, which is fair enough; can't rely on him for everything lol. So anyway, he has a really supportive family and I don't. I'm positive I will not be supported at home but I know that I can't just rely on my partners parents, especially with no job. Im pregnant but it is a bad time to have a baby? Or will things hopefully get themselves together in the next 9 months? I haven't told anyone yet.
