If you get a due date from an early ultrasound you can calculate this yourself. You can either count 38 weeks back from the due date which will give you the conception date or if you know how many weeks you are you can count back to when you would be 2 weeks pregnant and then this is when you would have conceived. So if you are 8 weeks pregnant, count back 6 weeks and this would be your conception date. 38 weeks back from Oct 30th is 7th Feb.
Pretty much any due date calculator online gives u the conception date.
how did u get the answer? is there a computation for that? :)
Im expecting says ur 8w3 days conceived feb 7 th if ur due date is oct 30
