To obviate the need to take daily tablets, injections have been devised which give a anti-fertility effect for 12-13 weeks. This contains a depot preparation of progesterone and is injected into your muscle. It however has the unwanted side effect of gain gain and delayed return of fertility.
Intra uterine devices are small devices which are left inside the uterus as a contrast measure. They are commonly known by the name Copper T as they have a winding of copper and are T shaped.
Currently many hormonal impregnated IUD's have been developed which not only prevent pregnancy, but also provide relief from dysmenorrhea and dysfunctional uterine bleeding.
Insertion of Copper T must be done by a health care provider and it takes less than 10 min to insert a Copper T. A small string is left floating outside the cervix so that its position may be checked by the women herself.
Intra uterine devices are perfect for women who are in monogamous relationship and who want to space their children. Prior to insertion of IUD pregnancy and pelvic infection must be ruled out. They provide sufficient protection for 2-3 years after which it will have to be replaced.
Some of the common side effects which are seen after insertion of IUD are pelvic pain and heavy periods. But these resolve by 2-3 months and very few women have to the IUD removed for these reasons.
If you do not desire to retain your reproductive potential you or your partner could go for a sterilization surgery. During this surgery the fallopian tubes are ligated on the ends so that the ovum will not be able to enter the uterus. This is a permanent method of contraception. Alternately your husband could undergo sterilization and it is much easier in the case of men. In men the tubes which carry sperms from the testis to the penis are blocked by tying them so that sperms are not present in the ejaculate. If your husband has undergone the operation then he must use a condom for at least six weeks after the surgery as a few sperms will be present in the ejaculate till that time.
There are many more methods of contraception, but I do not wish to cover them here for one simple reason. All of them have a very high failure rate and hence can not be relied upon. And in case of contraception, unreliable contraption is as good as none.
