Hello, I m a 30 yr old physically fit woman. I m experiencing a lack of appetite , nausea , frequent urination (getting up several times through night), and headaches. I started birthcontrol a little over a month ago. I wasn t great about taking the pill everyday, and I believe it threw off my period because it only lasted one day. I took a pregancy test 2 days later (I used protection), and it said negative, so I don t believe it s that. Is it possible the pill is creating these symptoms?
