I have a question i had my period twice in march lasted around 3days each. no period yet taken test and - could i be pregnant i was taking diet pills?

Diet pills: The diet pills, depending on which you were taking, could have disrupted your menstrual cycle but, if you were also having unprotected intercourse, you could still be pregnant and have done the pregnancy test too soon. Repeat the test in 3-5 days and, if it is still negative and your period hasn't started, see your doctor. Hope this helps.
