The line is a lot more visible than the picture shows. 
I should be about 5 weeks. This is my third pregnancy if I am. When I was pregnant with my daughter (first pregnancy) the lines were very faint like this. Our second pregnancy ended in a miscarriage. 
We have been trying since we lost the baby in October. I feel like I am pregnant. 
Why do you think?
