I am a Breast feeding mom and I was wondering do breast feeding prevents pregnancy? And it does for how long ?
While it is true that breastfeeding can delay the return of your fertility - especially if you are nursing a lot – it is possible to become pregnant while breastfeeding especially if you are not nursing exclusively (i.e. nothing other than breastmilk), baby is older than 6 months and/or your period has returned. If your period has returned with regular frequency it is likely that you are fertile again; however, if you experience short or sporadic periods, it is possible that your fertility has not returned yet. https://www.lansinoh.com/en/resources/getting-pregnant-while-youre-still-breastfeeding
