I’m 8dpo today I know very early still but yesterday and today I took a easy at home test , they all come with a very faint shadow like line … so I thought maybe I got a bad batch or something, so I go to Walmart buy a first responce I take it and with in 3-4 mins it shows the same shadow line … I was pregnant before sadly had a miscarriage I started testing early in pregnancy and that’s how all my test looked too until I was like 10-11 dpo it showed pregnant on a clear blue , but I posted before and people would say it was a ident last month I spent a lot of money on test cause of that .. but this time I’m not test are too expensive this is the last test till I’m 10dpo atleast … does anyone else see it ?
