Q. Pregnancy

In most pregnancy tests, the "C" (control) line indicates that the test is working correctly, while the "T" (test) line shows the result for pregnancy. If your test shows one line on T and no line on C, this suggests the test might be faulty or invalid because the control line (C) did not appear, which means the test may not have functioned properly. You should take another test to get an accurate result and make sure to follow the instructions carefully to ensure the test works correctly.
