Just thought I'd start this thread as I remember obsessing over how dark the lines were getting on my first pregnancy tests. I also remember using my ovulation tests as pregnancy tests and freaking out if they were negative.
Well, I'm currently 7 months pregnant and out of curiosity I did both a HCG and ovulation test this morning. HCG obviously positive but definitely not a dye stealer, and ovulation test probably the most negative I've ever seen one!
Hoping that puts someone's mind at ease if you're obsessively testing and comparing line colours.
