I took two pregnancy tests. on both the first line is very clear but the second line is extremely faint and can only be seen in the light. could i still end up pregnant or is it false? should i take another one but digital?

Can retest in 1 week: Home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, vaginal spotting, or medications. A test gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened). If done sooner, a negative result may be due to testing too early. Consider retesting with a different brand, after 1 week.
