When i first took my test the line wad really faint i didnt belive it took another and tht one only slightly came out darker and here i am 3days left to meet my lil girl :)good luck x
I used the digital clear blue to give me peace of mind when I only got a faint line good luck
If you already took several pregnancy test and you're still not sure ,my advice is that you make an appointment with your doctor,as soon as possible or if you don't have one go to the ER and they will either do another pregnancy test or have some blood work done to the detect the pregnancy hormone(hcg)
Mine was very faint at first. I thought it was negative and threw it in the trash, but I had a gut feeling I was pregnant and went back and checked it a couple minutes later and it was darker. Then the digital ones said pregnant.
First response rarely have evap lines, and definitely wouldn't get more than one. Sounds like you're pregnant, if you're really early it may just be how early you are, the darkness of the test isn't any issue at all.. congratulations!! :)
