I went off bc pill in april 13, my period was completely "regular" for 7 months. jan' i was 2 weeks late & now a week. what happened? no symptoms.

Late period: It's hard to say why it happens, but sometimes we are just late for our period. Things like medications, stress, travel, changes in your weight, can all cause a late period. If your pregnancy test is negative, repeat it once per week until you get your period, to be safe. If no period for a whole month, i would see your gyn doc to test for hormonal conditions that can cause irregularity.
