Faint lines

Julia • Pregnant with baby #1

Hey guys.. So I took a couple of pregnancy tests.. This week

3 had really faint lines And 4 were negative.

I took them 3-4 days apart from each other.

The last two I took today(evening) . The first one was negative and the second one was faint line

I don't really know what its supposed to mean

I took one in the morning as well and it was negative any ideas?
