Bought ultra sensitive pregnancy test strips to test after our one and only shot at IVF. I've had two "false positives" from 2 different batches now, both of which came up before the control line did and stayed on the test. The first one even had colour. All within the time frame. Took other tests and even repeated with the same strips and still negative. It is absolutely heartbreaking and I don't think they should be sold without a warning on the main page to let people know about these faint lines and false positives. I have 3 more unopened packs of these awful tests and don't feel right passing them on to someone as they are clearly not fit for purpose.
