I took my first dose today!! Did I do it right?

Okay so here is what I did, I opened the BAC water and the Reta 20mg and added 2 full syringes of BAC water I then mixed it in my palms then I filled 1mg =10 units and injected into the left side of my abdomen. I changed syringes when adding 100 units then 100 units of BAC water. Then a completely new needle when using it. Did I do it right? Then I put it into the kitchen fridge in the medicine part of the fridge. And I kept the BAC water with me (outside the fridge room temp). Did I do it right??

-I saw a bubble in the syringe I tried so hard to get it out. I couldn’t. How do I get it out??
