periods can be even late for a month due to stress etc.
so the most accurate diagnosis is to see a doctor. of course, you
can also use a preg kit... but that is not 100% confirmed. Quite
cheap one kit... less than 30 bucks?
In any case... never try your TCM or old wives' tale to abort. Seek
a qualified doctor, not some illegal quack.
Although I don't encourage abortion... if you have to do it, pls do
it w/o causing harm to the girl... the impact is really for
life.
