hi..my lmp was august 2nd, regular cycle ,3/28 days..I have a missed period....when I check UPT is negative,,,, please give some suggestions

A. Wait for one more week if you don’t get your cycle as it is meant to be then you should check with your doctor it could be due to disturbance in hormones also I would like to tell you that test kit at home that you take is not always hundred percent correct so you should take an ultrasound if you don’t get your period within a weeks time
