What if I have slight bleeding but not menstruation for 6 weeks with 2 negative pregnancy tests 2 weeks ago?

Hello, The first thing to do would probably be to plan for regular contraception. The use of the morning after pill as the only contraception is not recommended. In your case, it may have had an impact on the disruption of your cycle. Apart from that, you should not worry about the absence of periods for the moment. The small period of bleeding may have replaced your menstrual period, which means that your next periods may be delayed. In this case, I believe that you can expect to be menstruating again in just a few weeks. If pregnancy continues to worry you, you can take a pregnancy test every week until your periods return. Of course, I recommend that you take steps to obtain contraception more suited to your situation.
