The essence of Libertarianism is the ability to choose everything for yourself. Choose to get vaccinated or not get vaccinated. Choose to start a business or work for someone else. Pro-Choice is often wrongly percieved as "only choosing to murder all babies". Many in the Pro-Life crowd will only see things this way, not all, but many. What is so often missed is that just because a crime occurs, it does not automagically give someone else the Right to step in and decide that persons fate. One can oppose certain actions being considered a crime or not, but that is the extent of the power that they have over those who perform the actions they disagree with. Its the exact same argument with Pot, Speeding, Taxes, and damn near everything. "You dont have the Right to NOT pay Taxes", which just authorizes theft, however, things are usually taken a step further where the person making the demands wants to go in and take the non taxpayers money by force, and will as often as possible, seek Govt to enact violence against the non taxpayer.
Theres two sides to Pro-Choice. Those that have to make the extremely difficult choice of having an abortion could be percieved as the murder of a baby. However forcing that person to have the baby makes the person having that baby feel just as much a victim. Its a downward spiral of violence from both sides. Thus, instead of trying to make a person have and take care of said baby, a better more productive alternative would be to encourage non violent solutions such as offer adoption. Or maybe even better is to get off the "sex is sin" idea and promote birth control like Condoms. Then, there is a lot less conflict after the consequences of getting pregnant to begin with.
