is this menopause or pregnancy

[delicious2014]

well im trying to distinguish if im pregnant or perimenopausal.. last start date of my period was march 9 2017 nothing in April, nothing last week.  should i start prenatal and folic acid, or is this menopause starting. no  sore or tender breast just queasiness, feels like pressure on my bladder, fatigue, and i have to keep something like lemonade to settle my tummy. l
