Hey dear this a my first pregnancy too .I also have confusion abht that my friends advised me as v have to wait until periods missed because missed period s a first symptom.of pregnancy..so after 8 to 10.days of missed period she advised me to do home pregnancy test or go for beta hcg blood test by that u ll be sure abht pregnancy. I.also do test after 8 to 10 days of missed period too .U can try it dear ..best of luck
