I had a d and c on March 6 2012 and got my period april and may. My period in May was from May 30 until June 6 but I am usually not irregular and my period hasen't came this month it's been 4 days late. I did a home test last week and a blood test today and came out negative. The day I had relations was on June 19 do you think it's enough time for the tests to work well??? Can I possibly still be Pregnant or should the bood test tell me by now????????
