7 weeks pregnant but conception date is past ovulation?

[user1466690252]

Hello,
I am 7 weeks pg and apparently likely to conceive on the 22nd Dec. We DTD in the 22nd but I ovulated on the 18th? Must my ovulation date be wrong or is this possible?

Your ovulation date isn't necessarily accurate, if you used tests they show the LH surge day or more before the ovulation itself.

There's also some room for error in due dates and likely conception day estimates.
