Irregular Periods: Causes & What to Watch For

Question
Hi, I may have spoken with you before about being pregnant.  The day of my last regular period was May 9th, I did not have anything after that until July 2nd and it only lasted one day.  Do you think that I should be concerned. I have taken pregnancy tests and they have all been negative.  I though everything was ok until it only lasted for one day and was't heavy.  What could be the problem?

Answer
If you had some bleeding (even for one day), it probably was a period. You were due for your period on June 5 and again on July 2.  You probably merely missed your period in June and got one in July (at the correct time). If you have any doubt, and the pregnancy tests were negative after July 9, take a blood test for pregnancy (Beta HCG) at a lab. If the result is less than 5, you are definitely not pregnant.
