I’m pregnant and I’m not sure what to do.

First of all I’d like to say I’m really sorry, sorry to all the women/men out there finding it hard to conceive. Who have tried and tried and nothing’s working, those spending hundreds and thousands in hope to get their little one. I understand that this may be hard to read. Today I found out I’m pregnant, my digital test says 1-2 weeks, and honestly I’m not sure what to do. My partner isn’t sure either. We both want the baby, but we aren’t financially sure that we’re ready for another. We have a six month old girl and this baby wasn’t planned. We always talked about trying for another when number 1 was around 2. We live comfortably but aren’t at all rich, I just don’t want to put this baby or the one we already have in a bad position. Just need some advice
