The Pill

I've been on birth control on and off between having my kids. Originally I was on yaz but stopped taking it in 2009. I then had 2 children and now I'm ready to be on a good pill permanently. I recently tried lo loestrin Fe for 3 months and it gave me horrible anxiety and headaches. I am so much happier now that I've stopped it. What is a good low dose pill?! Any suggestions?? I've also been considering an IUD. Thanks!
