After giving birth, your body goes through lots of changes in the first few weeks. Although there are no specific recommendations for the best time to start having sex, many women wish to wait for about six weeks to recover from the birth of their child. Please consider that you may get pregnant without getting your period back. Therefore, if you do not plan to have another child, you need to use some contraception if you wish to have sex. 

In addition, it is a good idea to discuss contraceptive methods with your doctor before you give birth or soon after birth to choose an effective and suitable method for your health and lifestyle.
