I used a <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">due date calculator</a> to determine if I am pregnant when my due date would be and how far along I was. I’ve been like cramping on and off all day. My back is KILLING me middle through lower. I’ve else been getting nauseous at time. I don’t want to say its pregnancy symptoms because It could also be period but my period isn’t coming until at least 2 more weeks and I get symptoms a few days before my period. My boyfriend and I also BD before, on sept 1st, 3rd and through my fertile days. I’m really trying not to assume anything but it’s just weird to me.
