The contraceptive 'Saheli':
- Is an IUD.

- Is a post-coital contraceptive.
Solution
Saheli chemically Centchroman is a non-hormonal birth control pill. Instead of using the hormone estrogen to prevent pregnancy, it contains a drug that blocks estrogen.
Usually, increased doses of estrogen stop a woman’s ovaries from releasing an egg. However, by blocking estrogen in the uterus, Saheli alters the uterus’ lining, which prevents a fertilized egg from implanting.
