When do you know the line isn't from the pregnyl injection?

Hi,

I'm sure it's been asked before and I am my own worst enemy but at what point did you know if the 2 lines on the HPT means pregnancy or the pregnyl injection you had? I had the injection last weds as a booster but I know I ovulated the fri/sat before that. The clinic said I can't do a hpt till next Monday and to come for a blood test then.
I am so impatient!!!

Hi Razzberry. Good luck xx. I always tested out pregnyl so I knew when trigger was done which was about 10dp trigger at 10000miu. After that I tested daily. The only thing to do is try then watch for the line to get darker or lighter. But a slow form of torture. Wishing you the best xx
