Thanks for the info lads and lass (nicole).
Yeah, me and wifey planning to see doctor to check our kesuburan first before we proceed further with other methods. I suppose more like a hit and miss for the IFV. If miss, there goes your moolah. If kena... ok la twins, but kena triplets...alamak kasi pening sama both couple hahaha.
About the traditional method, yeah I've thought about it also but trying to find a reliable and trustworthy tukang urut is hard nowadays. Even in kampungs i think harder to find since not many inherit or learned the skill.
I suppose besides that, exercise and food intake also helps to increase the chances. Not to mention prayers as well
