And saying that you shouldn't be able to "force your way up a woman's uterus" is a silly argument.
How would you feel applying it to other arguments?
If you aren't a gun owner, you shouldn't be able to offer any policy suggestions on gun control.
If you aren't a minority, you shouldn't be able to have any opinion on civil rights legislation.
If you aren't a murderer, you shouldn't be able to give a policy opinion on what to do with murderers. Not all perfect examples, but surely you get the point.
Simply taking this position of "you don't have X characteristic" or "you don't have any 'skin in the game'" isn't how I believe anyone wants to operate a country. Simply having certain sex organs doesn't make your opinion any more or less valid.
It is a cheap tactic to try to avoid valid criticisms of your position. All that matters is this: either a fetus is a person or it isn't. If it is, then abortion is murder, and murder is and should be illegal. If you can prove that a fetus isn't a person, then the pro-choice position is correct. If you fail to prove that, then the pro-life position is correct. (Since a human life is at stake, then I believe that pro-choicers have the burden of proof. If there is a shadow of a doubt that it is a human, then we should err on the side of not murdering millions of babies).
