We've been over this. From the correct libertarian perspective abortion can not be murder until the baby is capable of surviving without the mother's help. Otherwise there is no moral difference between compelling her to carry to term and forcing a drug company to share its life saving medications. If you advocate for one, you must advocate from the other. I am a conservative, I am happily free of such slavery to philosophical consistency.
If you honestly believed abortion was murder, it stands to reason that this would be your number one political issue. You have made it clear that it is not.
