Unfortunate timing

I really love being pregnant, and I really want another baby. But unfortunately I’m not in a big enough place for a toddler and a baby. My fiancé (who is my baby’s father) our son and I live in a camper as of right now while we save up the money to buy our first home together. Everytime I see another pregnancy announcement on Facebook or anywhere really I get jealous or upset. Regardless, I am very happy for them. I just wish I could be in the right place to be pregnant again.
