So for the last two days I've had a dull to sharp pain in my lower left abdomen. It was on and off. I'm currently 12 dpo and expecting AF tommrow. The pain has subsided and stoped completely. I was extremely tired/nauseas/dizzy during the pain as well. There's been no bleeding that I've seen. I took frer test last night and it was BFN. So what do you lady's think? Implantation?AF? Would love some opinions/advice.
