I did another test and again barely visible stripe. On ultrasound it's not possible to get in, I live in a village, we don't do them here, I will go through a couple of days to the city, I will hand over So that's the question, isn't it really not appearing? And if this is not the first test within a few days and on all such a stripe barely visible, is it normal? Has anyone had this? Is everything normal at the end?
