Critigue-Is the Abortion Sonogram Law Unconstitutional?

My classmate Jessica Ready posted an article "Is the Abortion Sonogram Law Unconstitutional?"  This article is about a new abortion sonogram law. The law requires all women considering abortion to have a sonogram and listen to the fetus before aborting it.  The law was granted unconstitutional and was appealed.  The question Jessica asked was the abortion sonogram law considered to be unconstitutional?  She believes that it is not unconstitutional.  She agrees that the law was created for medical purposes and it is something women should be informed of.  By giving the mother information about the fetus the doctor is just doing his job.
I have to disagree with what Jessica.  My opinion is that a women should have the right to choose.  When an abortion is done some places already do a sonogram.  The women should have a choice if they want to hear about it.  I do not know if all abortion places are like that, but some are.  A doctor can suggest proceedures, operations, medications and you have the right to say no.  A sonogram or knowing the results from a sonogram should not be any different.  If a women is going in for an abortion she is not going to want hear or see anything that has to do with the baby.  I believe that the law was created not for medical reasons but in the hopes that by having a sonogram and showing the mother the fetus is the goverrnments way of trying to change the mothers mind into keeping the baby.  The doctor may be doing his job by dong the sonogram, but should be the women's job to decide if she wants the procedure done or to hear the results. 
I feel Jessica's article was well written and she does make a good point.  I do understand where she coming from.  I just do not agree with her.
