OK so I’m posting this because I just wanted to see what maybe some other people have experienced or thought of this. I know that you definitely don’t know if you have more than one baby until you get an ultrasound done . But I was just wondering if anybody’s experienced having such a dark line so early in the pregnancy and if there are lines get darker every single day. (I have only been testing every single day just because of my past miscarriage help my mind be at ease). I am currently four weeks and one day . The top pregnancy test is the one I took this morning and the bottom one is the one I took yesterday morning.
