Girl menstrual Problems.?

I'm 20 years old.

This month, I got my period on the 16 and lasted for 4 days. 11 days later Yesterday, On the 28th of this month, I started bleeding again, feeling cramped and bloated. I'm still bleeding. What could it be?
Its not a miscarriage, I took a pregnancy test.
Any idea before i see my Doctor?
Help. need advice.

your cycle is prolly just changing. its normal.

Loads of things can skew the menstrual cycle, stress for one, antibiotics, even flying. It is worth getting checked incase there is an underlying reason - but it may just be a blip, happens to almost all women at some stage.

It's hormonal.
Also, stress can be a factor.
I had my period start up again 6 days after it finished.
Don't worry..
If it happens a few more times..then go see a doctor.

o Honey that could be soooo bad you might have be bleeding internally it could be deathly my mom almost died from something like that

dont worry, i get the same thing sometimes. its perfectly normal to get two periods in one month.

Are u on the pill? I get irregular periods from it if I forget a few days

tampon

see a doctor, it's not going to be anything we can tell you
