Need advice from moms!

Erika
Hello all, this is my first pregnancy (and first post)! My husband and I have been married for a year but we were not planning to have kids for another year or so. I'm 4w5d now, I found out on 12/22. I wish we were excited about this, but we have so much we want to do before a child and we are seriously considering not keeping it. We're 29 and 32, so definitely mature enough to handle it, but I just started a great job and we do not have a support system close enough to us to help as much as we would need to both work full time. 
My question is to mothers out there- I feel like I'm about to plunge into the unknown, so how do you work and have a kid without having family close by? Does anyone seriously regret deciding to not have a child at a time in their life when it would have been hard? Is it worth all the work and being away from your family?
Any advice is greatly appreciated and I would be happy to provide more info if anyone asks!
(For the record, adoption is completely off the table, and I got pregnant very easily so I'm not worried about that in the future)
