Last period was beginning of april. May I didn't have it & still havent. Havent had sex since dec/jan but period continued. Am I pregnant since it skip?

May be. Did you have sex in 04/12? If you did have sex, then you may be pregnant. If you did not have any sex since dec/jan but period is skipping, then you need to see a doctor for blood test for other problems like thyroid.Or other organic problems. Stress can affect your period as well.
