I missed my period on the 27th of june and bleed on the 14th of july i took a test but it said negative am i pregnant ? missed period

It : It is unlikely that you are pregnant but the timing of the testing is sometimes too early. The most recent urine based test kits available to the home user are very sensitive and can actually pick up evidence or an early pregancy even before you have your period roughly 6-8 days avter ovulation (usually day 12-14 of a normal 28 day cycle) in the most effective testing. It is more likely that you simply did not ovulate as you normally do that month whether for stress or secondary to other common issues.
