Follistim left in the vial

Ka

Hey Ladies. Today is my 3rd day of stims.

The vial of Follistim was 300 iu

1st day pen set for 125 iu

2nd day pen set for 125 <a href="https://glowing.com/glow-fertility-program">iui</a>

Today I set the pen for 50 iu (I counted what should be left out of 300 ) and when I opened the pen to insert a new vial to put the rest of 75 iu, I saw that there is still liquid in the first vial. Did I do something wrong? I am worried.

I did myself the injections as my husband was out of town. And it was the first time, I watched many videos on YouTube before doing it, I was so stressed. So now I can’t understand why is there still liquid left :(
