No: 7 5/7 weeks estimated gestational age is time from last menstrual period by convention. It is similar to 5 5/7 weeks estimated from time of actual conception. The two weeks difference is adjusting for time of ovulation, usually ~14 days for most women.

Can you find out your pregnant the day of conception with pregnant test? 1 very faint positive 2 dark positives or does this mean im further along?

You can't: There is no way to detect if you are pregnant the day of conception. If you have 2 positive tests you are almost certainly pregnant, just further along.

No. Too soon.: No. If there are true pregnancy symptoms or a positive pregnancy test, then the woman was already pregnant from a prior ovulation (and did not actually conceive this time, 5 days ago).
