Hi doc,

I eiden, 24 years old. I am delayed for more than two weeks now.. i used to have my regular menstrual period on the 1st or 2nd day of the month.. this past month i used to sleep late at night for about 11pm then wake up as early as 4am..then play an online game ..and until now, i haven't feel any signs of getting mentruation (tenderness on my breast) but instead, i feel a flicker of pain on my lower stomach and i think i got an hyper acidity(crampled stomach, vomitting and burp) i got back pains sometimes and headaches. I have a problem also on my eyes and had lost weight recently.. does these things affect my regular menstrual flow?or am i pregnant?
