Anybody else have this birth control and gets no periods at all? I'm freaking out a little bit because it's been 3 months with no period at all, I have a 9 month old son and am NOT ready for another one yet. But here lately I've been moody as hell, had lots of hiccups in one days time (I only ever had a lot in one day when I was pregnant with my son), crampy, and feel like I'm gaining and not loosing any weight. Oh and feeling what I think is phantom kicks from my first pregnancy (can you still get those I months pp??? I don't know, I need some insight from someone else with this birth control.
