I would wait a few days and test again with first morning urine. Are you trying to become pregnant? If so, baby dust!! If not, you should look into other methods of birth control

I'm going through the same thing right now. Last month no period, I took a test and negative. Which we were releived because I am taking bc! But now I'm due for my period again we'll see what happens. Sometimes bc causes you to lose your period so I'm not too worried YET! But you are not taking any bc? If you are trying to conceive good luck to you and I hope the next test says positive! If not I would be getting to the dr to get a bc of somesort so you don't have something like this again. Good luck!
