I know that I didn't feel this way during my last pregnancy but it's understandable why I feel this way for this pregnancy. The first pregnancy was all sunshine and roses at first. Sure I knew that there was a chance of a miscarriage - but those things happen to other people not me, right?
The fact that the line is getting darker is comforting. I know that I won't be able to relax and enjoy this pregnancy until I see a heartbeat on an ultrasound, but for now, this helps.
