spiraling and maybe overreacting - did i mess up this dose/the vial?

i just took my second 2.5mg dose today. a few issues:

1. ⁠i drew a dose in a syringe but accidentally bent the needle while doing it. i put the dose back into the vial and redrew in a new syringe.
2. ⁠i was trying to get the bubbles out of the new syringe, that i put 13 units into. i couldnt get all of them out so because of that i ended up wasting some of the med before injecting. it was about 12 units, maybe even a little less :/
3. ⁠after i injected and removed the needle, i noticed that when i pushed the plunger of the syringe harder a bit more came out.

if my syringe is a little under 12 units (maybe like 11.9 units), did i underdose myself and will the med be less effective? am i going to run into issues where now i wont have enough medication for the rest of my doses because of the wasted product?
