 Hello! I am Dr. Himali Tekani. I am a consultant obstetrician and gynecologist at Manipal Hospital's Old Airport Road, Bangalore. When women are exclusively breastfeeding, they do not tend to ovulate and hence in the first 4-6 weeks, women do not ovulate and pregnancy is not a concern. After 4-6 weeks, ovulation can happen at any time and hence contraception should be resorted to. Now contraception in women who are breastfeeding differs a little from women who are not breastfeeding or who have not conceived at the time. Tablets recommended for these women are mini pills or progesterone only pills. These pills need to be taken on a regular basis every day and they have only a time span of 3 hours which is the window period. So if you forget to take a tablet more than 3 hours, then they need to use additional contraceptive measures for 48 hours. The same tablet forms are available in an injection. Now these injections are the DMPA injections which are given once every 3 months. The other forms of contraceptives which women who are breastfeeding can use are either barrier contraceptive that is the condoms. The other options included are the intrauterine contraceptive devices and when you look at permanent contraceptive methods, they include sterilization operations which can be either male sterilization or female sterilization operations. These can be done immediately after delivery or they can be done as interval procedures about 6 to 8 weeks later.
