Birth control...

Just wondering what you ladies would recommend! I've never used any kind of birth control so I was wondering what you prefer. I just had a baby, & I don't want another one any time soon. Before getting pregnant my cycles were extremely irregular and long. I went through a couple months of infertility and finally got pregnant after I had a HSG. I have my 6 week check up next week and I really don't know what would be best.
