all states have confidentiality laws that protect individuals in cases like this. Certainly, as you mentioned, your clinic has this policy in place. I would, though, keep an eye on these laws in the upcoming years. There has been a rising swell of interest from adoptee childrens groups to allow for an unsealing of records so that the child can find out who the parent is on the basis of "medical needs" - e.g. needing to know medical history and such. So, this is likely to be a conversation over the next couple of years.
Not to have you worry even more, of course. :)
