Mentrual Cycle Help [please].. Serious and mature answers only.?

I'm 15 and two months, and I haven't started my period yet.
Well yesterday I had some discharge that was bloody, so I assumed I had started my period.
There wasn't much, and then it stopped.
That's it.
That couldn't possibly be it, right?
My friend said that this is normal, and something of the same sorts happened to her, and then she started two months later.

My mom said I just might have a light flow.. but it couldn't be that light, right?
It was just the amount of putting your thumb and index finger together to form a circle. Maybe smaller.


If that WAS it, could that affect my ability to have kids?
Not that I was planning on it soon, but when I get older I want to have two or three children.
Can I have some advice?
Was my friend's advice correct?

Thank you all for such detailed and informed answers.
ALSO
Thank you for approaching the question with seriousness and maturity.
ALL your answers were SO helpful!
Thanks again.

perfectly normal-may take 6 months to get a regular cycle-this will no way affect you having children in the future.xx
