Thank you for your query.
As per your date of ovulation, it is slightly late for you to have implantation
bleed on day 29, but it could be possible.
The only way to confirm is to take a pregancy test.
As per your 28 day cycle, ovulation should have been on day 14, however it occurred late on day 17.
Hence, you should wait for a week more before taking a pregnancy
test, in case you do not have your periods by then, as only then will it be confirmatory.
All the best meanwhile, and take care.
