In America, a child becomes a citizen at the time of birth (acquisition) under certain conditions. But until the time of birth, the fetus is not technically a U.S. Citizen. Does it then still have the constitutional right to life, liberty and happiness?

You don't have a Constitutional right to "life, liberty, and the pursuit of happiness". That famous language was contained in the Declaration of Independence, not the U.S. Constitution. 

The Constitution is the highest law in the U.S., but the Declaration is not law at all. Courts will sometimes use the Declaration to guide their opinions, and the holding of their opinion is law, but the Declaration is not. 

Although life, liberty, and the pursuit of happiness is not law itself, you may find some of these words effectuated in the Constitution. For example, your right to liberty is embodied in various amendments, including the fourth amendment's limitations on search and seizure and the fifth's protections against self incrimination and guarantee of due process.
