Last week I got my period and I usually start my period two days before the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I’m going to but this month I started on the night that it said I was going to start. The first day was all dark brown spotting and then that night I got cramps and started a period. When my period ended I started feeling really tired a little nauseated and my breasts are tender. Is it possible that I’m pregnant? Would I have had a period like that and still be pregnant?
