I took an at home pregnancy test last night and got a super faint (but still totally there) second line. I had a dr. Appointment this morning for something else so I decided I’d mention it at the appointment and see what the dr said. I took another test first thing when I woke up and got another super faint second line. I mentioned this at my appointment so they did a urine test and said it’s negative. Could it just be the test strips they use or did I just get faulty tests from the store???
