I took two clear blue test, at different times, both have that faint vertical line. I wAsnt sue of my results so I took a first response teat, it also has that faint positive line. I was still unsure so later on I took a digital first response test, never used a digital before either. Well the digital came out no. I’m so confused because I am 8 days late now and I have regular periods. I have had very sore breast as well. What do you think?
