Try not to stress, SC. There are a lot of reasons the test may not have been as dark as you were expecting. For one, you tested with afternoon urine which probably wasn't concentrated like FMU would be and therefore could easily be the reason for the lighter test line. I like to remind myself that the pregnancy test doesn't determine how pregnant I am, it just tells me I'm pregnant. It's easier said then done though, I got myself all worked up with my pregnancy with DS over the darkness of the lines and I didn't learn my lesson as I found myself getting worked up over the darkness of the lines this time around too. Maybe put the tests away until Monday when you go to the doctor.
Also, the crying thing is one pregnancy symptom for me that DH thinks is hilarious. We were watching a show and I started crying and it really wasn't anything to cry about. Though I will say this symptom hasn't seemed to go away ever since I got pg with DS. I can cry pretty easily over things that I really don't know why I'm crying about.
Anyways, how is everyone doing? Loopey I know you were only 10 dpo when you first posted in here. Hoping everyone still has a sticky bean!
