You need to see a doctor... do it soon.

When did you take the pregnancy test? If it was awhile ago, sometimes a positive result doesn't show up for several weeks. Since your cycle is normally regular, and you have now missed two periods, try another test and check with your GP. If you are pregnant, you'll want to get set with a midwife... if you aren't pregnant, you'll want to try and find out why you have skipped two periods.
