Does infrequent sexual intercourse help minimize the chance of pregnancy?

I have sex only once or twice a month as we don’t want to have a baby. Infrequent sexual intercourse means a slim chance of pregnancy. Is it correct?

Infrequent sexual intercourse lowers the chance of pregnancy. However, you can still get pregnant if sexual intercourse happens around the ovulation period. Besides abstinence for unwanted pregnancy, the best way is to consult a family doctor or obtain family planning service from the Family Planning Association or the Maternal and Child Health Centre. They will help to find the contraception method that most suitable for you.
