Haiii, congrats on the twins! Normally doctor akan suggest around 36-37 weeks for twin pregnancy, tapi it really depends on how things are progressing, some of my mum friends delivered earlier sebab complications or baby position, ada juga yang made it to 38 weeks. Best thing is to discuss dengan your doc pasal your specific situation, kasi dia check your cervix and babies' development, then barulah dia boleh give you a more accurate date. Take care of yourself, and jangan stress too much ye, your body will let you know when it's time!
