my reply is kinda messy.. i'm never good with organising my
words.. 
it all depends on the situation.. i have frenz who have gotten
married at teh young age of 15, 18 cos of pregnancy.. their family
is supportive, and it's so much easier to cope for them.
once, my sister popped the question to our mother.. "wat would u do
if u realised that one of us is pregnant?" (*there are 3 daughters
at home) My mother said, she could help look after the baby,
provided that she doesn have to work, so the "mother" can go ahead
to do wat she wants, she'll be there..
that is the kinda support u need from the family if u wanna give
birth to the baby. u have to noe that u can go out to work or study
while ur baby is in safe hands. u have to noe tat no matter wat
happens, no matter how big the stress is, ur family will be there
for u..
being a mother would mean that u lose the freedom to do things w/o
considerin the pros n cons.. u have to start being responsible for
ur action cos the moment u did the act w/o protection, u're already
being very irresponsible, not to mention gettin urself pregnant.
irresponsible to urself, n the baby u carry. my mother is still
doin things w/o considerin the p&c.. thats y i can tell u its
no good.. u dun wan ur kid to be the one tellin u wat's rite n wats
wrong do u? when u're supposed to be teh one they turn to for
advice nt the other way round
one more thing would be... when u were childless, u'd be thinkin..
100 can last me for how many days.. at most, i'll eat instant
noodles everyday.. but when u're with a child, u can't do that
anymore... teh child/baby needs nutrients.. they need food

being a single mother isn't easy, but being in a marriage just
becos of pregnancy isn't that good either.. I've seen it.. my
family's like that.. My mother raised all of us single-handedly, we
have a father, they're married but he doesn contribute at all. sch
fees, livin expenses n everything were forked out by my
mother..
n my mother blamed me for that... geez..
