14 days late now, several negative tests. Took this one today and it was negative for the first few minutes so I stepped away. When I came back it showed this. I have an IUD so I was surprised by this result. The test was laying on an angle so I think that’s why the dye moved a little. Thoughts? Have had cramping every day for an entire month with no period. Bottom test is from last week, top is the new one.
