I found out that I was pregnant from a home test on December 20th 2010. I started taking tests the first week in December and every time was a negative. My last period was October 23 2010. Today I went into my ultra sound and the doctor told me that I was 6 weeks to date and I am due August 28th 2011. She said I needed to come back in 2 weeks because there was no heart beat and then she told me that I should strongly consider my options of what to do if there is no heart beat. I do not know what to be concerned about as everything I have herd and read is that a heart beat may not be detectable until 8-10 weeks. Should I be concerned and consider other options.
