Are my period regular?

I have NO consistensy near my periods.The lone consistency is that they are never consistent! One day they can be a light of day early (this happen two months ina row but never again) but every other time for 8 years (I started at age 10) they have be late by any 1 day or 2 weeks.There have never been a time when they hold come with indistinguishable space inbetween.Normally I am 3 days or so late.Is this conventional?It's so inconvenient and will it mean I will be unqualified to get pregnant? Go on the pill, you'll know when to expect your period and they won't be heavy.
why are you asking this again? di the other 20+ women who answered it 5 mins ago not give a hand you enough?
