How to know if I'm pregnant after a trigger injection and follicle growth?

Determining whether you’re pregnant after a trigger injection and follicular growth involves understanding how these treatments work and the appropriate time to take a pregnancy test. The trigger injection is often used in assisted reproductive techniques to induce ovulation. If successful, ovulation typically occurs around 36 hours after the injection. Since you mentioned that you’re on the 25th day of your cycle, it’s been 11 days since the injection, which might still be a bit early for a home pregnancy test to show accurate results due to the presence of the hCG (human chorionic gonadotropin) used in the trigger injection itself. The hCG from the injection can take about 10-14 days to clear from your body. To reduce the risk of a false positive result, it’s generally recommended to wait at least 14 days after the trigger injection before taking a home pregnancy test. This way, you’ll minimize the chance of detecting the hCG from the injection rather than from a pregnancy. If you’re eager to know sooner, a blood test performed by your doctor can often detect pregnancy earlier than a home test, but it should also be timed to avoid the influence of remaining hCG from the trigger shot. In any case, give it a few more days if you’re considering a home test and if you have any doubt or need guidance, reaching out to your healthcare provider is always a good step to ensure the most accurate testing and advice tailored to your situation.
