Most birth control methods is Myanmar are very afforable. You can find a range of condoms that cost anywhere between 100-3000ks for a pack. One packet of birth control pills can cost around 200-2000Ks depending on the brand and where you buy it. Both of these methods are widely available and can be bought at most drugstores.
However, IUDs are probably the most cost-effective form of family planning in Myanmar. Although the inital cost is around 10,000-30,000Ks, IUDs last for 5-10 years (depending on the type). That means if you have an IUD that lasts 5 years, you are spending a maximum 6,000ks on birth control per year or 500ks a month!
