The question asked contains the answer ... you conceived 7 weeks and 2 days ago . Since there are 7 days in a week, multiply 7 times 7 and then add 2. 7X7 = 49 +2 = 51. Grab a calendar and count back 51 days and you will have an approximate date of conception. It's not all that accurate but it is really close.
