Since the trigger shot contains hCG, you may be able to get a positive on a pregnancy test without being pregnant if you test too soon after the shot. Experts at the Mayo Clinic recommend waiting at least 2 weeks after the shot to take a pregnancy test.
Can hCG trigger shot cause false positive?
Typically, it takes about 10 days for the synthetic hCG in these trigger shots to clear from your blood and urine. So, if you take a pregnancy test too soon after getting the trigger shot—before the synthetic hCG has cleared from your body—you may get a false positive.
How long will trigger shot give false positive?
Depending on the dose, it can take about 14 days for the trigger shot to leave your system. So if you take a pregnancy test sooner than 14 days after your IUI and get a positive, it may be a false positive from the leftover hCG in your body — not from new hCG produced after implantation.
Does ovidrel cause positive pregnancy test?
Ovidrel is similar to the hormone that is detected by pregnancy tests; therefore pregnancy tests will be falsely positive for up to 14 days after the shot. Do not take a home pregnancy test within 2 weeks of any Ovidrel shot.
Can anything else trigger a positive pregnancy test?
It’s possible to have a positive pregnancy test even if you aren’t technically pregnant. This is called a false positive. It’s sometimes caused by a chemical pregnancy. A chemical pregnancy occurs if a fertilized egg, known as the embryo, is unable to implant, or grow, very early on.
Can anything affect hCG levels?
There are many factors that affect the levels, and the normal range varies hugely between individual women. Your doctor will be able to monitor your hCG levels for you if you have concerns. Even if they remain low, there is nothing that you can do.
How long after implantation does HCG rise?
If you are pregnant, your body needs time to develop detectable levels of HCG. This typically takes seven to 12 days after successful implantation of an egg.
Does trigger shot cause pregnancy symptoms?
The most common dose is 10,000 iu but the dose can range from 3000-20,000 iu. Side effects of the hCG injection will mimic pregnancy. Most commonly patients will complain of mild nausea, headaches, fatigue, breast soreness, irritability, abdominal bloating or uterine cramps.
Does hCG shot help implantation?
Human chorionic gonadotropin hormone (HCG) is a hormone important for pregnancy. It helps make the uterus lining more receptive to implantation (of the embryo). Some studies suggest that injecting HCG into the uterus may improve implantation rates.
How long does hCG from ovidrel stay in system?
Following subcutaneous administration of Ovidrel®, hCG is eliminated from the body with a mean terminal half-life of about 29 ± 6 hours. After intravenous administration of Ovidrel® 250 µg to healthy down-regulated females, the mean terminal half-life is 26.5 ± 2.5 hours and the total body clearance is 0.29 ± 0.04 L/h.
Can ovidrel cause twins?
Call your doctor if a boy using this medicine shows early signs of puberty, such as a deepened voice, pubic hair growth, and increased acne or sweating. Using this medicine can increase your chances of having a multiple pregnancy (twins, triplets, quadruplets, etc).
Can hCG be high when not pregnant?
An elevated β-hCG in the absence of viable pregnancy can occur for multiple reasons and has a broad differential diagnosis including miscarriage, ectopic pregnancy, pituitary hCG production, trophoblastic disease and phantom hCG.

Can you be 5 weeks pregnant and test negative?
Although it’s less likely, it is still possible to be pregnant even if urine and blood tests come back negative. If you still believe you are pregnant after receiving negative urine and blood test results, your medical provider can perform a transvaginal ultrasound to determine whether you are pregnant.
Is it possible to get a faint positive and then a negative the next day?
False positive pregnancy tests are very rare. Most women will never have one. In fact, false positives are so rare that if a woman does have a positive test and later has a negative test, she should assume she had a very early miscarriage. If you test positive, try testing again a day later.
