The last 2 months i have period pains constantly, bloated etc i have had a period and done 2 tests which r neg what could this be?

Depends: Would have to know what tests were done, but if you are still having symptoms, you should follow up again, and if still not getting answers, seek another opinion.

Many options : Irregular periods are one of the most common problems obgyns treat. If this is one time problem it usually resolves on its own. If this is a recurring problem you should be evaluated. There are many options available to help regulate the menstrual cycle. Schedule a visit. Home pregnancy tests are very accurate. They are the same tests used in a doctors office. You can trust the result.
