Am i Pregnant Or Not ?

I Really dont want to jump to conclusions but . I have floppy weight and sore chest the black line on my stomach tiredness no appetite a weird vomit taste in my mouth pain in my lower stomach i get headaches once in a while more energy than ever. i bleed for three days but i usually bleed for 5 days and missed the first two days . it wasn't heavy like a regular period just a small flow . i have bowel movements alot now but not constant.
