Missing period because of pregnancy or menopause

It could be the onset of menopause. I went thru mine early, so never say never. I am 51 and haven't had a period since 2002. (lovin it by way) Your body may be starting to give you little signs, like messing with your periods. You may get one this month, you might not. You could miss 3 or 4 in a row, then all of a sudden bleed for days.
I would wait until you miss your next period, (if you do) then take another test. Your Doctor can do blood work to see where your hormone level is at. Mine were totally depleted.
Or...you just could be pregnant!!!
