Confused!!!!!

Been to the docs today I explained that I am trying for a baby and that my AF has not come since the 8th October and I stopped taking cliest on 13th September had a what I call real AF and then I had a 4 day on 8th October heavy two days then really light two days and she said you don't need to worry for at least 6 MONTHS and if you still have not had a REAL AF come back and we will do tests. !! Yes I am 22 but I felt very judged by her has any one else had that experience ???
