I need some advice as what I should do because instead of my lines getting any darker seems to be getting lighter. I asked for a beta draw but had a response that as long as my Pregnancy test was positive I didn't need one, but I'm concerned now because yesterday my hpt was a little bit darker than today. Yesterday's test is on the left Today's is on the right. I know HCG doubles every 48-72hr but shouldn't it be getting darker than lighter? Or do you think it's the same, Help!!
