erm, it probably is not as romantic as you think it is. You could get one of those pregnancy vest things they use to show teenagers what it feels like. You could get one on the internet.
For many it probably feels like crap, especially in the last trimester. You have to pee lots, your bones hurt as the ligaments loosen, you can get heart burn, your back kills you, you get short of breath, your balance is terrible, your temperature control is bad so you overheat easily, you might get a rash, your mucus membranes go bannans so it feels like you have a cold, you might feel sick all the time (it ain't just the morning), smells become over powering, constipation, bad gas, you might not even be able to pull up your own nickers. Just when you are trying to sleep your baby wakes up and starts having a party in there. It is no picnic.
