Wanting baby number 2..

I am desperate to be pregnant again, my baby is only 6 months but i miss being pregnant and always wanted 2 babies close in age. Took me nearly 2 years to get pregnant before, & had a miscarriage, so it might take ages again so dont want to wait and then for it to take years again.. but we currently dont have a home, im sleeping on my mums sofa for a few nights a week then at my MILs the rest of the week, we barely have room for our one baby so having another one is clearly not an option right now, which really upsets me 😞
