Maybe (not) . . .: If you're 4 weeks past your last menstrual period (and you've been engaging in unprotected sexual activities), then yes, you might be pregnant. In the states, home pregnancy tests can be purchased at the local drug store, even grocery store. I don't about how it's sold in india. You might need to ask your doctor to run the test & check for you. Next time, use protection if you don't want pregnancy.
