"My body my choice" always was a bad justification because you obviously have to look at the interest of the child too if you count it as human life as many do. If you ask around you don't find too many people that wish they were aborted. The same logic can apply to wearing masks because it can affect other people aside yourself. But many argue here that the responsibility to protect yourself with masks is on those that want this protection but in case of abortions the child cannot defend itself or its rights.

To be honest I believe part of the problem is self-inflicted. Many conservatives had already made their peace with the issue and some media personalities unnecessarily picked up the topic and some people made a fool of themselves in a way so that the opposition only needed to show around their behavior to garner more supporters against abortion. It is probably naive to believe that the argument is about ethics instead of partisanship at this point.

I am for legal abortions and against mandatory masking (most of the time, there are situations where wearing a mask is just sensible), but I don't see these topics intersecting very much. Abortions will happen if they are legal or not. To minimize suffering a legal and medical responsible way is required.

But it is still an ethical question to allow it or not and intrinsic to almost all ethical considerations is that there is no clear right or wrong so I don't see a solution if either a vast majority supports it or not or opposing political factions collaborate on the issue.
