Anyone test positive 17 days after DPO

Anyone test positive 17 days after DPO or longer? I'm late and took 4 pregnancy tests and all negative. Last pregnancy 2 months ago I was positive 9 days DPO but lost pregnancy after 8 weeks... I'm never late and don't know why I'm late if I'm not pregnant :| 
Just curious if it's possible to not have a BFP late...
