Trigger shot advice

Is it normal for a trigger shot to leave my system in 6 days? Im testing out the trigger shot and tested this morning and it’s stark white. Seems like that’s really quick to leave. Last one I did, it lasted up to 10 days.. has this happened to anyone? I’m worried that I didn’t get the full dosage because I forgot to check for air bubbles when we did the injection. My husband keeps telling me to stop stressing about it but I can’t help but think.. 😳😒
