Conservatives disagree on a lot of things, where abortion is concerned unity is limited to overturning Roe v Wade so that each state can set its own laws. Overturning Roe v Wade does not ban abortion, it simply allows individual states to decide, safe bet how Cali and NY would go, ditto the Dakota and Kansas. Were that too happen the left would be welcome to engage in that very rare habit amongst them, opening their own wallets for charitable contributions, and set up a pool to provide airfare or whatever to people seeking travel to another state for that procedure. For my own part, I would at least like to see a waiting period on it, I'd consider it ironic and appropriate if it were legally set to be exactly the same waiting period on guns, as I consider both to be life or death issues one should try to force a cooling off period on to consider options. Nobody, excepting persons who already own a bunch of guns maybe, needs to be buying a gun on short notice, if they are in immediate peril they should call the police. Ditto, nobody should be in a position to get an abortion the same day they find out they're pregnant, it is absurd to even consider such a person would by default be in their most fit state of mind. The same logic applies as with guns.

As for birth control, there is absolutely no unity on birth control, most of us are strongly in favor of maximizing availability of that, and NO ONE even vaguely non-fringe is discussing banning birth control, there are just some (a minority) who frown on its usage like they do smoking or drinking. You'll hear about some of us wanting to restrict birth control, that is actually true, we don't want anyone getting any chemical, rather than physical (condoms, etc) birth control without proper oversight so people are actually getting safe medicine. That gets over-stated a lot. We're not happy with the controls on what is very definitely not a 100% safe, 0% side-effects group of drugs.
