Conception

Tamara
So, please no judgement, I was not in a relationship in October. 
Intercourse: October 7th 14
Period/bleeding: October 29
Intercourse: November 1st & 14th
Ultrasound dating 9w 6d January 8th
Ultrasound dating 14w 2d February 6th
EDD: August 5th for both ultrasounds 
Conception: November 12-16th
Is it possible I conceived in October at all? My doctor told me absolutely not but I still have it in the back of my mind something went wrong on both ultrasounds, even though I know they can't be more than two weeks off.
