Could be Menopause or pregnant, either one.
As I am sure you know, There have been instances of women getting Menopause in their teens or twenties. although rare as it is.
For pregnancy tests, They are generally a waste of money in the first couple weeks, They are known to give false readings both ways.
I would wait till around a month or so before I started to let it change my life. 30 days is not that long, and It's not going to make that much difference to you in the end.
Good luck either way.
