daphne/caitlyn,
i also put on quite a lot. i put on abt 5kg for 15 weeks now.
everyone say my tummy very big loh, considering that i am only 15 weeks looks like 5 mths leow.
daphne,
think your hb is not wrong leh, cos my hb almost every night also try to hear, and sometimes he can hear the bb's heartbeat. he told me that the bb's heartbeat is very fast.
initially, i also like you, dunno its mine or bb's heartbeat!! hahhaa..
