Unsure.. please help.

I’m not sure if I want to do an abortion. I am about 5 weeks and I have a 17 month old. Finding out I was pregnant again was surprising and abortion was an considerable option as I’m not done with university until next year and me and my partner are doing well financially rn but I have no idea how well we will be doing if I bring another baby here and on top of that we’re still living at his parents home... but my partner has been looking for a house. And on top of that my insurance with my parents ends when I turn 23 in January so I would have to some way find medical care... We’re still young at 22 years old and my partner says we have all the time in the world to have another one but also telling me he will support my decision if I want to have another baby but he told me to think about it. I feel like I’ll regret doing this. I feel very emotional. I’ve had one medical abortion before and I’ve had to pray to god to forgive me and to make me a mom for a second time when I’m ready but I don’t feel ready but I know the grief is going to eat at me and I’m just so anxious and I haven’t told anyone... I’m weighing the options and everything seems to point to abortion logically but I feel ill thinking about my appointment tomorrow. I feel like god will not forgive me or I won’t forgive myself or I will feel resentment towards my partner and I have the fear of not being able to conceive when I actually plan on having a baby... I look at my son and I want to give him a sibling but I don’t think the time is right.
