HPT results

I took my first hpt 5dp5dt and got a very faint positive. I have continued to take one hpt every morning and the positive line has continued to get darker. So, it appears that I might actually be pregnant! I am cautiosly optomistic and too afraid to be happy. After two failed cycles and one ruptured ectopic....I need to see the heart beat before I start to let myself relax. My beta is scheduled for Monday (Memorial Day).
