I hadn't been paying attention to when my cycle was actually due to arrive. The cramping was just like I always get within two days of starting my cycle so I started wearing a pantiliner thinking it was going to start any day now. then I checked my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> and it said I'm not even due until this weekend. I have never had this happen before. I know what ovulation feels like because I get that every month but this was different. Has anyone else ever had what I thought was period cramps a week early? And if so what was it?
