What is a safe birth control method after giving birth?

Ask
Hello doctor. My wife just gave birth for nearly 2 months, then my husband and I had unprotected sex. I also let it out, because I learned about amenorrhea birth control methods. But today, I saw on the internet that many mothers also had unwanted pregnancies when they were only 2-3 months old. I'm so confused I don't know what to do. Ask your doctor for advice. If it's really not safe, how should I prevent pregnancy? We've only had sex for 48 hours. Thank you doctor for helping me.

Answer
Hello. It is difficult to determine exactly when your wife will get pregnant again after giving birth. However, if your period starts to return (about 6 weeks postpartum), your wife is likely to be pregnant again. If ovulation occurs, your wife's pregnancy rate will be very high.
In case you have sex for less than 48 hours, your wife has just given birth and is breastfeeding, you can use emergency contraceptive pills for breastfeeding with 2 main ingredients: Progestin and Estrogen. The advantage of this type of birth control pill is that mothers can still use it during breastfeeding (under 1 year old) without worrying about affecting the baby's health. However, the most important side effect your wife may experience from taking hormonal contraceptives is a decrease in milk production.
