What is the physical feeling between a bloat or a baby bump? which is softer? which is harder? does a bloat reduce size when lying down?

Pregnancy v Bloating: Being pregnant would cause your abdomen to slowly get larger over time as the baby grows inside you. You should also be able to know if you had unprotected sex and are not having your period anymore-that would point to probable pregnancy. Bloating is usually increased gas or fluid retention that may come and go, and generally feels different than a growing baby inside you. See the Doc.
