AF 11 days late! Please help!!!

My AF is 11 days late, and I have been getting negative results on HPTs. I got my blood test (qualitative HCG) done 5 days after missed period, but got that as negative. My cycles generally are 30-34 days and never missed one. Did anyone have negatives for few weeks after they got pregnant and then got BFP? What did you do if you were in similar situation earlier? I either want to get my AF so I can move on or get BFP soon. Please send baby dust my way!
