Hello, I'm new and I need help from all of you. Im a 23 yrs old girl, I have very irregular period each month, in one month I could get my period on the 5th, and the next month on the 19th and usually my period only lasts for 3-4 days. Im not sexually active. I've been having brown spotting for the last 2-3 months, usually it occurs between periods, and not close to the period time. It lasts for 2-3 days, and not very much. Anyone know what this is? Thanks a lot.

I think its time you visit your gynea

Thanks for the advice.
Do you know why this happened? Could it be because of the stress/is it normal?

No, I don't have sufficient knowledge on these issues.
But to put your mind at rest, visit your gynea and ims your she can answer any of your questions :)
