No period for 6 months, went to the doctors around the 4th month and he told me to come back in 2 months time..

I was going to make the appointment but much to my surprise I got a period, was over the moon lol but since then I have not had another one. I'm not on any birth control pills, I came off those last year in May time and my periods were fine up until the beginning of this year, I'm not under stress or anything!
