I had to re-apply as I changed jobs for a while. Unfortunately it does take a while, I think it took me 4 weeks and I had to go to my doctors to get them to sign the form saying I was fit to work! Call the GDC and explain the situation, don't wait for them to get in touch. And insist on working on reception or something until your registration comes through if it wasn't your fault...it costs a bit more too, I thin I paid £140.
Hope you get it through and enjoy your return to work
