Hello Priya, Thank you for the question. Its very right on your part to consider contraception now that you have resumed sexual activity. Breast feeding is a good contraceptive in itself but not foolproof. So its better if you use some other forms of contraception even while you are breast feeding. Preferably use a condom each time. If you dont want to use a condom then you can take a progesterone only pill (PoP) or you can get an intrauterine device (IUD) or even a progesterone depot injected. In all these cases there is small chance of baby receiving some progesterone except in condoms and IUDs but that has no effect on the baby. These are all prescription drugs and it will be better you visit your gynaecologist who can prescribe the method you choose. Till then the safest method is using a condom. Hope this helps. Take care.
