Trigger shot question

Hannah • Pcos. FET #2.

I’m supposed to trigger with novarel 10,000 units. The specialty pharmacy only gave me 5,000 units. They are no longer open until Monday. I contacted my nurse to let her know what happened and she contacted the doctor. They said to just use the 5,000 unit trigger and we’ll hope it works. Does any one have any info they can give me as far as their experience with 5,000 units ? Will this still work ?
