Pregnancy Timeline: Determining Conception Date Based on Dates & HCG Levels

Question
If I had sex on july 5 or 6 then again july 12-20 had a positive blood test july 25 hcg level of 37 ad a due date of april 9, 2011 when did I get pregnant

Answer
I did a conception calendar at http://www.ivillage.com/due-date-calculator
So it said that if your due date was April 10, then you ovulated on July 18. So probably when you had sex between July 12 and 20 was when you got pregnant. Now I am not a medical doctor so just know that. Did you have your baby already?
