I'm on my third cycle (after coming off the pill). The first was 28 days, the second was 34 days, and now I'm on day 36 of the third cycle with none of the usual "AF is coming" symptoms.
HPT have been negative but if AF doesn't arrive, at what point do I say 'okay, this can't be the pill extending my cycle indefinitely' and see a doctor to get a blood test...another week, two weeks?
