Kitten, firstly congratulations! I just wanted to try to relax you. I was in the same boat as you this time last week, I tested positive on Wednesady, AF not due till Saturday...was wishing I hadn't tested, thoughts of chemical pregnancy etc! But Saturday (AF day) came and went, not a sign of AF, and I'm now starting to relax...and I even told my close family yesterday. Saw the doctor Friday, day before AF day, and he confirmed and gave me a due date of 21.06.09. When I told him of my worries he said he could do a blood test but didn't think it was necessary as my tests were defo positive (as are yours seem to be!)
My tests got darker as I went, and are now darker than the control line! I got through the last week, AF day came and went, and the week did fly by. I know it's easier said than done, but try to chill. As for the cying...that's one of my pregnancy symptoms!
