No period!!!

My last period was Aug 27-31!!! I had a surgery on Sep 6 because I have endometriosis!!! I was told after the surgery that I could easily get pregnant!!! I haven't had at all since then!!! My doctor told me that it could take up to two months before I got another well it's going on three months and I'm a little worried about it!!! I don't no rather to make another appointment or if I should wait it out some more!!! I just wanted to know some of y'all opinions on my situation!!!
