Patient's Query

Hello doctor,

How long does it take for hCG to show up in the urine in a 42 to 45 days cycle? My period is delayed by 12 days. When should I take a pregnancy test?

Answered by  Dr. Kanani Darshan Jayantilal


Welcome to

I read your query and can understand your concern.

Typically, hCG (human chorionic gonadotropin) can be detected in urine around 10 to 14 days after conception. However, in longer cycles such as yours (42 to 45 days), ovulation and subsequent conception may occur later, so it is possible that it may take longer for hCG to be detectable in your urine. However, since your period is delayed by 12 days, I would suggest taking a pregnancy test now to check if you are pregnant. If the test is negative and your period still has not arrived, it may be a good idea to take another test in a few days.

It is also worth noting that delayed periods can occur due to a variety of reasons, including stress, changes in weight or exercise habits, hormonal imbalances, or medical conditions.

Hope this helps.

Feel free to contact me for further queries.

Thanks and take care.
