Seguro Popular.....is this valid???

We registered at SP one week ago. Made many copies of the affiliation page. As far as I understood, we need to see a doctor within three months of registration. So we went to the SP clinic in San Antonio, today. The nurse there, asked us both if we were diabetic, or had high blood pressure...no examination at all. We answered "no" and "no". she then gave us a booklet each, in which she filled out our names, and address. ...no policy number. We asked to see the doctor, as we were under the impression that this was necessary to validate the policy. She replied that it was not necessary. Can someone please comment as to whether or not we are legally in the system. Thank you.

After registering and given our paper a friend and I thought we had to see a doctor.  We then went to the Chala clinic and they said no.
I stopped in the Ajijic clinic.  Same answer.

The procedure for Seguro Popular is not the same as for IMSS, where you should see a doctor to start your IMSS file.

Thank you, everyone, for your replies.
