ok so my period had never been 100 percent regular. I started when I was like 10 and every since then it's been crazy. at one point I had two periods in one month(but that was when it was still normal for it to be irregular) now I'm 18 and my periods are still weird. I usually have one every month but I never know exactly what day it's coming. I just started my period yesterday after skipping a whole month( no I'm not pregnant I took a pregnancy test.. well two) and this is probably the second or third time this has happened since I first started my period at 10. i haven't seen a doctor about it and I would like to know what everyone thinks. thankyou
