Hi, my period is very regular every month. My Sept period is on 24 Sept but I'm having some brownish spotting before my period came on 30 Oct. My period last for 5 days, first two day was kinda heavy but then the rest is very light. 2 days after my period stop, i start to have spotting again but this time is red color spotting.
The spotting is sometimes a little more then sometimes less. It has last for a week now. I do not have any cramp or pain for it. My breast is kinda heavy just like when about to have period. I having sleeping disorder and headache, meaning that I feel tired but i cannot sleep.

Is it possible that I'm pregnant? When can i do pregnacy test?
I dun know whats wrong with me.
Appreciate anyone who know, please advise me!
