Positive? Clomid & Trigger Shot

Has anyone here been on clomid and then had a trigger shot? I had my trigger shot 13 days ago and just took a pregnancy test and it's positive!! Still thinking whether it might be a false positive though. 
Would love to know for those that had a trigger shot, how long did it take to get out of your system and if it was more than 13 days was it this positive? 
I'm waiting for my doctor to let me know what's the next step but would love to hear from you all! 😄
