Need HELP!

I guess some of you know my problem.I had my period 5days earlier and I saw light brown for 3 days and then nothing. I still have tender breasts and lower backpain feels like presssuring downwards,and bleeding gum when I brush my teeth. Today was supposed to be day 7 of my period but weirdly I am clean with some yellow discharge(I see usually at the very end of my period).I couldn't have time to buy a test so I kept my morning urine in closed bottle and tried the test after I bought it but it gave me negative results.Is there still a possibility that I can be pregnant or there is something going on with me that I should worry about. HELP:confused:

You need to use the test first thing in the morning. There could be deposits in the jar that you kept your urine in that made the hcg, if you are pregnant, undetectable.

If you still get a negative in the morning, it would be wise to seek medical advice from your doctor or health care practitioner.
