Could you be pregnant if last month period was 2 weeks late and then came and left and then came back 5 days later for one day this month its just dark brown discharge and a negative test?

If you were pregnant, you would be at least 5 weeks from conception date from your dates above. A pregnancy test will start to show positive around 2 weeks after conception. If you tested negative, I would say you are not pregnant. Hello. This doesn't sound like a normal period. It sounds like irregular period bleeding or pregnancy bleeding. Because the test was negative its most likely irregular period bleeding. But do see your doctor for a blood test to find out for certain if you are pregnant. Good luck.
