Doctors' responses

Yes, your positive test could very likely be due to the Choriomon rather than an actual pregnancy, especially since you took it on 28-03-2026 and tested positive within about 10–12 days. Choriomon contains hCG, the same hormone detected by pregnancy tests, and it can remain in your body for up to 10–14 days (sometimes a bit longer), causing a “false positive.” Since your period is not yet due, it is too early to confirm a true pregnancy. The best approach is to repeat the test after a few days or, more reliably, get a blood beta-hCG test and see if the levels are rising (which would suggest pregnancy) or falling (which indicates leftover injection hormone). Overall, this situation is very common during fertility treatments, and you’ll need a little more time and follow-up testing to know the actual result.

Hello dear See false positives result can occur since the product you are taking contain beta HCG. The duration is minimum 10-20 days This is same hormone which is tested for pregnancy So false positives result can occur Regards

Yes, a positive pregnancy test after taking Choriomon can indeed be due to the medication itself. Choriomon is a brand of human chorionic gonadotropin (hCG), a hormone that help trigger ovulation and supports egg release when used as part of fertility treatments like Menopur. Since pregnancy tests work by detecting the presence of hCG in the urine, taking Choriomon can lead to a false-positive result if the test is performed too soon after the injection. This is because the hCG from the injection can still be present in your body and cause the test to indicate a positive result, even if pregnancy hasn’t occurred yet.

Usually, hCG from the injection can take about 10-14 days to clear from your system, depending on the dose and your metabolism. Thus, to obtain an accurate pregnancy test result, it’s often recommended to wait at least 14 days after the hCG injection before testing for pregnancy. If you’re concerned or want to confirm the pregnancy, it might be best to consult with your fertility specialist or general practitioner for further guidance. They may suggest a blood test to more accurately measure your hCG levels, which can help differentiate between residual hCG from the injection versus hCG due to early pregnancy.

Hello

Yes, Choriomon can definitely cause a positive pregnancy test after using Menopur, especially if the test is done within about 7–10 days of the injection. This is because Choriomon contains hCG, the same hormone that pregnancy tests detect.

Since you took the injection on 28-03-2026 and tested positive more than a week later but before your period is due, the result could be: • A false positive from the injection still in your system, or • An early real pregnancy, particularly if implantation has already occurred

The key factor is timing. The hCG from Choriomon usually clears from the body within 10–14 days, but in some people it can last a bit longer.

What to do now: Repeat the pregnancy test 48 hours apart. If the line becomes darker over time, that suggests a true pregnancy. If it fades or turns negative, it was likely due to the injection. The most reliable confirmation is a blood beta-hCG test done about 12–14 days after the injection or after a missed period.

Seek medical advice promptly if you develop severe abdominal pain, dizziness, or heavy bleeding, but otherwise this situation is common during fertility treatment and usually just requires repeat testing to clarify.

Take care
