Cycle day 99??!?

De

AF is currently 9 1/2 weeks late.. all hpts have been negative and my blood work came back last week and hcg was only a 2 . My thyroid and everything else was perfectly normal. Ive never been more than a day late and my cycles were always 28-29 days.I’m completely at a loss. Could I still be pregnant? I’ve been nauseous and dizzy and extremely tired..but I’m not sure what to think?
