Hi I am 19 years old and I have been with my bf for 2 years and 9 months. We have been sexcualy active and my periods are never on time they are always late like late to the point I am buying a pragnacy test to make sure that we are expecting. Everything has always come back the same but I hate worring everymonth that we might be. Is it possable that my period will always be late and never get to a regular cycle?
