Super late and negative?

Melanie
Okay so my last af started March 30th and I took a few test and all look negative, not sure what to do, could I still be preggers even though the three test I took say negative? My af has never been this late. - http://glowing.com/community/topic/72057594040219786?utm_source=android&utm_medium=shared_to_third_party&utm_campaign=glow_community
