Im new here and waiting...Did a pt @ 8 dpo...BFN

Big surprise there. This is only my first cycle ttc but with ds1 and ds2 It only took one cycle. I have been queasy for a few days and had twinges in my abdomen along with some cramping but not much. I dont remember what it was like with the other 2 pregnancies, but Im hoping its not all in my head. I have very little cm but its clear. Not temping or anything. But to the best of my knowledge I O'd on the 1st. Since I only have a 27 day cycle I have to wait until Sunday. Booo! BD A LOT this month so I am hoping for a BFP soon. I dont know how much longer I can wait before I go POAS crazy! Anyone else doing the same thing?
