Answer -
If your period started on June 20, and a pregnancy test after July 24 showed a positive result, you are definitely not pregnant. Provera will bring on your period if all of your reproductive organs are working.  You must take the Provera twice a day for five days, whether you start bleeding or not. Provera will not interfere with a pregnancy if you are pregnant, but you are not pregnant if the pregnancy test has been negative. If you do not bleed after taking the Provera, it may mean that you do not have enough estrogen production. Discuss all of this with your doctor. Provera will not interfere with a pregnancy test either. If you are unsure, take two blood pregnancy tests, 48 hours apart. If the results are less than 5, you are not pregnant. If the results double in 48 hours, it indicates a pregnancy.

Answer
The pregnancy test was 0.28. As I mentioned before, any test less than 5 is a negative pregnancy test. Therefore, you are definitely not pregnant. Provera is the medication you should take to bring on your period, as your doctor mentioned. Your frined (who is in medical school) does not know what they are talking about. Provera will not mess up your cycle. It merely brings on your period. AFter that, it should get back to being regular. If your period does not return to a regular period, you may have to go on birth control pills for awhile to regulate your period. Don't listen to anyone who has not had training. Your doctor has, in addition to medical school, been a resident for 4 years and has been in practice.
