My period has never been regular except when I was on the pill. I haven't been on the pill for quite some time and I'm currently 21 days late. I have been late before but I don't think I've ever been this late. I don't really have any symptoms except for the occasional slight nausea (which is normal for me anyway). I took a pregnancy test this morning and it was negative.
Is it possible the home test gave a false negative or is that fairly unlikely given that I'm already 3 weeks late and have no symptoms?
