Pregnancy Info HOME

Hi All, I am 30 y/o. I had a tubal ligation Jan '16. No issues. My period has stayed the same. Coming at the end of the month & lasting 3-4 days. This was until Feb I had my period 02/27-03/01 & then again 03/28-03/29. It was heavy the first day, the next day it was heavy but by the night it stopped. The past 1 1/2 wks I am extremely tired yet an increased sex drive, stomach bloated, nipples tingle,, need to pee more,headache ( 1 wk and unusual bc I never get headaches) , irritable. I took a test 4 days ago it was negative. Can I be pregnant or could it be something else? Any advice/info is appreciated. Thank You.
