5 1/2 weeks of third pregnancy and showing already
This is pretty common, especially with subsequent pregnancies. Your body remembers how to grow to accommodate your pregnancy and it is getting ready. Fluid retention and gas bloating are also very common at this stage of pregnancy. Your baby and uterus are still very tiny and hiding behind your pubic bone. It will still take some time for your actual baby to be showing. You might want to consider when and how you are going to announce your pregnancy because your body may give your secret away soon!
