What is the best birth control for pp mums?

Bárbara • I`m 29, and I have a beautiful baby girl born on May 30th, 2017 ^^ I also have a dog named Oliver and I love him lots!

So my Dr. told me I need to choose a new form of birth control because she says the mini pill might not work well now that my baby is 11 months old. Does anyone know if this is true?

Also, I would like to know which one you think it's better after having a child?

Another pill, the shot or the implant?

This is dumb but I don't want the IUD because it scares me lol so any suggestions based on your experiences would be great! Thanks!
