Hi there,This is Dr Basu, experienced Internal Medicine Specialist.I am here to address your concerns and provide great service.
That is a dilemma.
You had ovulation on Aug11th. Hence Aug13th intercourse is more likely to cause pregnancy.
But your pregnancy is 7 weeks 5 days. That means you conceived much earlier.
The conception date comes around July 27th.
Hence, the period you had on July 27th was likely implantation bleeding.
Any sexual intercourse around that time July 27th or before should be the cause of this pregnancy.
Aug 6 and 13th can be ruled out.Best wishes,It was my pleasure to help you today.If I have answered all your questions, Please rate my response Excellent (click on the 5th star on top).Please bookmark my profile for fast, reliable authentic answers!This is the link to my profile:http://www.justanswer.com/medical/expert-mysticdoc/
of course this pregnancy cannot have started in July.
7 weeks and 5 days today correspond with the beginning of last period on 27th of July and ovulation around 11th of August. As sperm can survive up to 5 days, intercourse on August 6th cannot be totally excluded, but August 13th is much more likely. Ultimately only a DNA-test could give you certainty.
Wish you all the best for the further pregnancy, kind regards,
Dr. N. Scheufele
