*****????AM I PREGNANT????****** plz ppl i need advice?

Am i pregnant? I posted a few wks ago about my period gettin shorter and now im more than a wk late.? My last period started on April 26 and ended on May 1 and my period still hasnt come on...I thought me and my bf were being very careful and use protection(always). I started working a 6wks ago in at waterpark..does the intense heat and change in my daily rutine or sleeping patern have anything to do with it? and my have been tender for the past wk and a half....and having abdominal pains
