Confused??

Ok so I peaked on the 29th of last month. Had sex on the 30th. Got my first positive on November 8th(very faint). The doctors are saying im 6 weeks 5 days. Does that sound right i had an ultrasound done two days ago. No fetal pole was detected so I'm just worried about it. Is it too soon for the fetal pole still? Also my test did get darker.
