Am I out for this month?

I had a temp dip at 9dpo with some spotting and cramps which I attributed to implantation, I've now had a dip at 12dpo. I've been having serious fatigue, a lot of gas, dizziness, headaches and a strange stretching/tugging feeling in my lower abdomen. Is there a chance I could still be pregnant or am I out for this month? My period was due yesterday but nothing and I not having the symptoms I usually get when she's coming. Has anyone else been through this and did they end up pregnant?
