Baby number 2??? Maybe??

I only took a pregnancy test this morning and it showed up pregnant my period is 6 days late... I guess I’m looking for a little support my SO of 9 years and I have a 2 year old and love him we know we want another one some day but right now we are looking at buying a house and I’m afraid we couldn’t afford it. He doesn’t know yet that I took test at all. Just looking for a little guidance will having a baby right now ruin our chances of getting a house??
