What should I do

So I’m 19 and pregnant again well with my second baby I have a 2 year old boy who very hyper active and a huge mommy’s boy and the other day I found out I was almost 5 weeks pregnant with another baby . I still live with my mom and currently looking for a job and to move out . When I told the dad he was happy and wants to keep the baby as much as I do . He’s supportive and willing to get me and my son a home all together with our new baby when it comes . When my brother found out he made me tell my mom and when I told her she immediatelytold me to get an abortion and when he told his mom she said the same thing . I’ve been crying the whole weekend because I know right now isn’t the time for a baby and their arguments are valid but we want to keep the baby . We think that even before we find out the gender we can work hard and move out get ourselves together and have the baby but I don’t know what to do I’m conflicted because we did try for the baby but stopped hen we kept getting negatives and after a miscarriage and now that we finally got this baby unexpectedly we’re happy and want to keep it but I feel like everyone’s so against it with so much negativity I don’t know what to do everyone says I’m young and this and that and they’re right but I’m also a responsible parent so idk .
