How long B4 trigger shot is out of system

Hey ladies! I've read some very conflicting info online about how long the trigger shot takes to get out of your system. I know that it also depends on the strength of the shot. My script was for 2500 (which I think is the lowest dose) anyways. Just wanted to get some info from you ladies. Would love the input! Thanks and baby dust to all of you struggling with infertility. My heart an thoughts go out to you!
