11dpo symptoms

So I'm still waiting for my bfp. And today while i was at work. Only me and the pregnant girl could smell the scent of hotdog. I thought i was crazy and we both don't know where it was coming from cuz nobody was currently eating around us. Then i got really bad headaches and migraines Today, had slight back pain, and took a brief nap after i finished my lunch today. Yesterday i felt like some slight pulling and twinging on my left side (wondering if that was implantation) I'm really just taking it one day at a time. I never wanna over excite myself of what could be. So let's hope for the best. AF is due in 3 days.
