Is this normal? I got my period today although I shouldn't have got it until Tuesday (this makes it 5 days earlier). Do you think that's normal or should I be worried?

Mine is only 18 days long and has been for years now. I've been told by two different gynos that this is within the realm of normal. I think the government should subsidize me for tampon costs. You're probably fine, too, but you should see a doctor just to make sure.

i actually started keeping track of mine, and it's like, 31 days or something.

a normal cycle is anywhere between 21-31 days. I got worried when mine started happening every 21 days ( 3weeks) instead of every 4 weeks but my gyno said unfortunately, that is normal.

It just sucks when you get your period 2x during one month because of that
