My pregnancy test had a very faint control line and a dark line for negative. could i be pregnant?

Read Directions : Most pregnancy tests have a control line to ensure a good test so you are correct, the control line should be visible. However, most tests have a second line which appears if your test is positive. Some have "+" or "-" signs. Read the directions again to make sure you're interpreting your test correctly. You can also see your doc if you still have questions. Take care.
