Okay Confusing

Alrighty then, I am now 2 DPO. I was taking the OPK's and I didn't even realize it but the stick was the darkest on the 6th. So yeah, I am wondering if anyone knows how soon you can experience symptoms. I really feel just weird and I'm not sure if it is sleep deprivation or if I'm getting sick. I really hope it cuz Im PG though. I will go in on the 15th like I said to get my blood drawn. So yeah I got off work at 8am and then went to school and now I'm tired so I will blog later if I can.
