you probably a moment ago changed your eating behaviour or sleeping habits or something else external to be exact causing your biological clock to be a short time out of wack. if it continues for more then a week next you should consider seeing a doctor just to be undisruptive.
at home pregnancy tests even for the best ones across the world can't be taken more then four days since your next expected term. however the doctor can give you a pregnancy tryout using your blood which can generally be done sooner afterwards the at home ones.
