What would you do?

I’m pregnant with my 3rd baby in 3 years. My oldest kid is 2 and my youngest kid will be 1 the beginning of April. I’m not in the best financial situation and I don’t have a big enough house for my kids. I stopped taking birth control because of the negative effects it had on my body. I track my ovulation to make sure I’m especially careful those days. I use spermicide and this past month I was extra extra cautious and took a plan b, which failed me 😩😭. I’m torn because a part of me wants to have this baby and another side is like the time just isn’t right. My first two were planned, this one here was not apart of the plan until after my wedding in August... I need advice! Please be nice!!
